Otherwise opening a Grid editor can cause ApplicationConnection to get
stuck in 'active' state even if no actual scroll position processing is
ongoing, which in turn causes TestBench delays when it tries to wait
until ApplicationConnection indicates that everything necessary has been
processed.

This is needed to get /UIDL working behind a reverse proxy. Without the change pathInfo would be "/UIDL" but prefix would be "/UIDL/" in line 105.

Hibernate Validator 5+ requires

Fixes #10437

* Add 1px buffer to Escalator column natural widths.

The purpose of the buffer is to avoid subpixel handling issues,
especially when zoomed in or out.

In case fractions need to be adjusted for browser compatibility, round
up to ensure the contents have the space they need.

Fixes #12048

* Fix to natural column width calculations in Table footer.

NOTE: components within row generator are not an officially supported feature and can cause issues within your application.

Fixes #11235

* Update release-note template for 8.12.0.alpha1

* Add a regression test for Table's RowGenerator feature.

There used to be a TB2 test for this once upon a time, but for some
reason that never got converted into a TB3 test before getting removed.

* Explicitly remove old dataprovider listener when new one is set

If not done, this can cause memory leakage

* Formatting

* Fixed coding style

* Take into account further scenarios

Component maybe detached permanently and thus data provider listener needs to be remove in detach. Also if this is only momentary remove from layout add back cycle, re-setup is needed in attach, in case it was not already setup before attaching by setDataProvider.

* Change super.detach() call order

* Added null check to getDataProvider

* Setting dataProviderListener to null on detach

* Removing listener only if it exists

* Fix

It is possible when Vaadin 8 is used with MPR, that ui.getCurrent().getSession() returns null.

There might be pending requests in the queue when a resync request is
made (e.g. through a theme change). This can cause conflicts if the
resync request is handled immediately. Therefore the resync request
should also be added to the queue and only get resolved when
doSendInvocationsToServer() gets triggered again.

Fixes #11954

- If the Grid has any columns with non-fixed widths, the presence of a
vertical scrollbar affects the column width calculations. Horizontal
scrollbar should only be shown when actually needed.

Fixes #12049

Delayed size changes caused by added or removed scrollbars should be
taken into account.

Calculate number of the week in the year based on Date. Note, support for "ww" is missing from GWT DateTimeFormat and java.util.Calendar is not supported in GWT, hence DIY method is needed.

Issue #8707, slightly modified cherry-pick of #10492

Added a toggle in Table (and thus TreeTable) where you can explicitly
disable multiselect touch screen detection. This allows you to work
around issues on hybrid devices that have both a touch screen and a
keyboard where you don't want automatic simple multiselection applied.
