Liferay 7.3 series have kernel version 10.x, i.e. limit needs to be extended from 10 -> 11

Fixes: https://github.com/vaadin/framework/issues/11938

Use 403 Forbidden instead of 410 Gone when session expired. Also prevent caching in more cases.

Fixes #11108

onConnect was allways called with websocket = false. I think this is wrong, since if there was connection loss in websocket, now connection cannot be re-established in websocket mode.

Fixes: https://github.com/vaadin/framework/issues/11299

This bug may have been manifesting in other ways as well

Recently similar fix was done in Flow as well, see: https://github.com/vaadin/flow/pull/7489

Vaadin is not affected by CVE-2014-3558, the purpose of the update is avoid false positive alarm.

Fixes: https://github.com/vaadin/framework/issues/11903

Should use a StringBuilder to accumulate strings in a loop, to avoid the performance cost of repeatedly constructing strings.

Browsers differ in what they return as the content of a visually empty rich text area (RTA). Accordingly, RTA sanitizes these different values ensuring an empty string is returned to the framework. However, existing sanitization criteria doesn't work for Firefox 74 and Internet Explorer 11.

This fix appends the sanitization criteria of Firefox 74 and IE 11, ensuring an empty string is returned to the framework for a a visually empty RTA.

Fixes #10420

Column widths shouldn't be calculated between the clearing of cache and
re-populating it, but be delayed until the cache has some content again.
The calculations should only be triggered immediately if no rows are
expected.

Fixes #9996

* Updated LayoutTester screenshots for IE and FF.

* Fix an issue with frozen column count and unhiding.

Unhiding logic should take into account that there can be hidden frozen
columns that are not the column currently getting shown.

Fixes #11909

There is no need to reset the sidebar for every column that is set
hidable within the same roundtrip. Because no other layouting depends on
the sidebar contents, we can safely delay the reset until all columns
have got their hidabiity status updated. As a bonus point, when the
reset itself is delayed, the headers have time to get populated and the
sidebar button's height can be determined immediately at attach. The
reset ensures that attach is called every time a column's hidability is
changed.

Fixes #11892

Removing ElementResizeListeners from an element makes it unmeasurable
and clears any saved measured values. Adding the listeners back makes
the element measurable again but doesn't add it to measuring queue.
Measuring needs to happen or any updates to expanded components within a
layout (without changes that would trigger full re-measuring of the
layout itself) lead to broken expand size calculations with any fixed
size elements assumed to have no size.

Fixes #10734

* Further tweaks to ComboBox popup positioning.

- Updated a comment and renamed a private method for better clarity.
- Blocked unnecessary position updates.
- Added a test for #11866 / #11894.

* Adding missing setPopupPosition(left, top);

setPopupPosition(left, top); needs to be called in order to top position to be set

Fixes https://github.com/vaadin/framework/issues/11894

* Rewrote debouncing of onResize

* Reverted previous commit

* 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

Fixes: https://github.com/vaadin/framework/issues/11875

- 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).

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

Fixes #11843

* Test tweaks

Less fixed waiting times when there are ways to check that the operation
has been performed. This will hopefully improve the stability a bit.

* Merge branch 'master' into updateTests20191218

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

- Use BrowserStack workaround for proper sendKeys functionality on IE11.
- TreeGridBigDetailsManagerTest: allow two pixel discrepancy in expected
scroll position to accommodate IE.
- TreeWideContent: switched from raw type to type inference.
- ValoColorPickerInputFormatsTest: switched equals comparison to correct
way around.
- ResponsiveLayoutUpdateTest: updated screenshots for IE
- ColumnCollapsingAndColumnExpansionTest: updated screenshots for IE
- ClosingWindowWithBrowserFrameShouldntGenerate404Test: test is
incompatible with IE driver, excluded from tested browsers. In manual
testing IE doesn't get 404 in the logs with or without the fix
associated with this test but there are other client-side exceptions
related to focus handling in either case. However, those are out of
scope for this particular fix and should be investigated separately.

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
