* 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

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

- 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

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

Fixes #11718

issue in #11343 and #11385 is not reproducible on top this patch
Three different bugs are involved in this fix:
we bring the old fix(#11094) back and fixed the other related issues:
1) allow adding the same new item after dataProvider got reset, This is cause by the client side parameter `LastNewItemString`, it saves the value added before resetting. 
2) clear the pending newItem eagerly, so that the same value will not be added again.

* Fixing autocompletion issue with ComboBox on newer Chrome versions

Newer Chrome versions do not work with random number hack to prevent auto completion, but it finally supports autocomplete=off.

when the view is scrolled.

Fixes #5043

Icon load detection code does not handle error events so broken images
will cause tests to fail forever. In other cases also, it seems very
rare to need icons to be loaded before interacting with a combo box. If
there really are use cases for this, it would be better to have a method
to query if all icons are loaded so that special tests can use this method.

Fixes https://github.com/vaadin/testbench/issues/916

Fixes #9071

Fixes #9079

Currently the reset method resets the lastFilter as well and then the logic thinks items don’t need to be refreshed when popup is reopened.

Fixes #7790

Fixes #8778

Synchronises parts of compatibility package code to match 7.7
Picks suitable patches for 8 code as well

Fix since tags for the server and shared modules and new types in client.

* Reduce ComboBox initial requests

Use initial fetched data on client side,
do not request data from server side for each time popup is opened.
Fixed initial filter being null for ComboBox on DataProvider,
causing unnecessary size & fetch for not-changed filter.
Fixed ComboBox sending default filter unnecessarily to server.
Fixed wrong page indexing in VComboBox -> ComboBoxConnector.

Fixes #8496
Fixes vaadin/framework8-issues#488

* Fix last item missing

When pageLength was 0 and nullSelectionAllowed,
the last item was not shown. Tried to sensify the API
for total suggestions versus total suggestions + null selection item.

* Fix ComboBox selected item updates

Handles changing of ItemCaptionGenerator or ItemIconGenerator,
need to update the selected item caption and icon separately.
Previously it worked because all data was sent all the time to client.
Doesn't fix the issue, when selected item is updated with refreshItem(),
and it is not on the active range that will be sent to client.
For that, ComboBox would need a separate notification about item update.

* Updated screenshots

Running formatter:format will format all files in a submodule using an
embedded Eclipse compiler (based on Neon SR1)
according to the regular formatting settings file.
