Fixes: https://github.com/vaadin/framework/issues/11897

* Removing code causing the  trouble

Removing code that was apparently not needed in previous fix and caused regression 

Fixes: https://github.com/vaadin/framework/issues/11895

* Added feature to test UI

* Added test case

* Adding missing import

* Fixing test UI

* Enable DateField

* Fix logic of lexicographical comparison of DateField range end

Fix logic of lexicographical comparison of DateField range end with large year numbers ( > 9999)

Fixes #11881

* Added tests

Purpose of dateFieldRangeYearDigitsIncrease() is to test that rangeEnd works correctly on 4 to 5 digits change boundary

Purpose of dateFieldRangeYearBigNumbersPopupOpens() is to test that popup opens also when there is more than 4 digits in year

* Fixing typo

* Add error message

* Set the date of the field in test

* Fixing

- DateFields with month or year resolution should not get their date
reset to current date if the field's state is updated (e.g. by changing
read-only status or adding a range).

Fixes: #11864, #11605

* Update to 8.11-SNAPSHOT

Fixes #10854

* Removed outdated spacer height update from removal process.

Fixes #11856

* Fix to RadioButtonGroup readOnly handling.

Updated the connector to use the widget's enabled and readOnly handling
as intended.

Fixes #11843

Expand ratio and spacing can cause ComboBox to miscalculate its own
position while layouting is still ongoing. Popup should not be
repositioned in such circumstances in order to avoid incorrect
intermediate states.

Continues on #11718

Fixes #11838

Changes:

1. Close a window when maximized button is focused and ESC is pressed
2. Add additional check for a close button to react to the ESC key press
3. Rename a private method `onCloseClick` to `closeWindow` to allow code re-use

If first attempt at scrolling doesn't succeed it's unlikely that
continuing to wait is going to make any difference. Cache should be
populated before triggering any actions that depend on the row being
visible, otherwise it should be enough to trust that scrollToRow
actually scrolls to row and once scrolling is done the row is as much in
view as it's going to get. This way we don't get into a situation where
Editor never opens because it's still waiting for that one last pixel
that can't be achieved thanks to browser zoom causing rounding errors.

Continues on #11672

The attempt gets blocked later down the line in any case and never
reaches the server, but sending it messes up TreeGrid's internal state.
It gets stuck waiting for the resolution of the blocked call that can
then only be resolved by server-side sending its own expand/collapse
request programmatically. Until that happens no further expand/collapse
attempts will get sent to server even after the TreeGrid has been
enabled again.

Tree is also affected as it is built upon TreeGrid.

Fixes #11822

There is a bug in TwinColSelect loging, it retains selection by indexes not by values after being sorted when new item has been added. This is a fixed by changing updateListBox method to retain the selection as it is being called after selection is being done.

Fixes: #11287

- If an open popup is reset to its default position on every update from
the server before getting adjusted again to the actual expected
position, on heavier applications some of those intermediate positions
might get rendered. If the ComboBox is positioned at the right edge and
the popup contents are longer than the input field (i.e. popup should
open to the left, not right) this might cause flickering.
- Setting the default position is only actually needed when the popup is
opened in order to give it a baseline, otherwise it's better to simply
adjust the position if needed.

Continues on #11718

* Fixing issue with Push stopping working in some circumstances

If new request is attempted when resynchronization is ongoing, the Push will stop working. This patch fixes the issue by aborting handleJson if resynch is already ongoing. 

This PR supercedes https://github.com/vaadin/framework/pull/11786

Fixes #11702, #7719

* Call onResynchronize() in MessageHandler

* Optimizing

The checkbox for selecting all rows only selects all the rows that have
not been filtered out. Changing the filtering does not change the
selection or the checkbox state so assuming that all rows are selected
simply because the checkbox has been checked cannot work.

Fixes #11479

The filtering needs to be delayed, otherwise it's performed before the
new filter text is available and the old filter text is used instead.

Fixes #11779

- If the Grid has frozen columns zooming can cause the regular column
cells to be ever so slightly out of sync with their corresponding rows.
This difference is not noticeable to naked eye but is big enough that
it's possible to hover over the row instead of the cell, which causes an
assertion error and a big ugly error popup. Switching to logging retains
the information delivered by the assertion error for developer purposes
but makes the end user experience smoother.
- Can be tested manually with GridColumnFrozenColumn test UI.

Fixes #11198

* Added 1px tolerance to ScrollbarBundle's internal sanity check.

Requiring exact match can cause this check to fail when the browser is
zoomed since rounding is involved. This can in turn block some features
like opening of Grid Editor from working until some more scrolling
happens and the minute inconsistency is fixed.

Can be tested manually using GridEditorUI, depending on the environment
different amounts of zooming may be required for the problem to
manifest.

Fixes #11672

- The new top row logical index should always be within the logical
range and high enough up to avoid leaving a gap if possible.
- Added regression testing for using the different scroll destination
types for scrolling to the top and to the bottom by index.

Fixes #11732

Fixes #11718

* Make sure expanding/collapsing updates expected cache size.

Fixes #11749

* Merge branch 'master' into issue11749

* Upload should preserve MIMEType after first selection

Fix #11698

Automated test is not run locally, need to continue with it

* Remove unused imports

* Add sleep time in testing purposes

* Getting a new instance of an input, after file is downloaded

Exclude IE from tests. Throws https://stackoverflow.com/questions/23883071/unhandled-alert-exception-modal-dialog-present-selenium , but checked manually and it works

* Catch and handle IllegalStateException

Fixes https://github.com/vaadin/framework/issues/11730

* Renaming variables

- Initial implementation erroneously assumed that
ScrollDestination.START would only be used for scrolling up and
ScrollDestination.END for scrolling down. That's obviously not what they
are for, otherwise everyone would be using ScrollDestination.ANY.
- Moved actual scrolling to within the helper method that originally
only calculated the new scroll position. Parent method became too long
otherwise.

Fixes #11706

Updated row and spacer handling for Escalator.

Main changes:
- Spacers are only maintained and checked for rows that have DOM
representation, and not at all if there is no details generator. This
gives notable performance improvements to some particularly large Grids
- Escalator no longer tries to trim away any rows that don't fit within
the viewport just because a details row gets opened in Grid. This leads
to some increase in simultaneous DOM elements, but simplifies the logic
considerably. For example opening or closing details rows doesn't
require checking the overall content validity beyond the details row
itself anymore, but some repositioning at most. There are also no longer
any orphaned spacers without corresponding DOM rows.
- Spacers are better integrated into the overall position calculations.
- Some public methods that are no longer used by Escalator or have
changed functionality or order of operations. Any extending classes that
tap into row, spacer, or scroll position handling are likely to need
reworking after this update.
- Auto-detecting row height is delayed until Escalator is both attached
and displayed.

* Add explicit handling of ctrl-a

Fixes https://github.com/vaadin/framework/issues/11678

Fixes #10741

- Escalator should notify when an existing details row is moved to a new
index.
- Grid and DetailsManagerConnector should update their internal indexing
when details manager index changes in Escalator.

* Fixes #11642. ComboBox with pageLength 0 should be updated if DataProvider changes

* added comments, fixed imports

- Initial fix attempt interfered with selection events, added regression
testing for those and found a better way to ensure shift selection works
on IE11 also with Windows 7.

Fixes #11608

* Update release note for 8.9

* Missing Since

* Adding "v-grid-editor-selected" stylename in editor cell wrapper element when Grid is opened on selected row.
