* Update copyright year range.

- These plugins cause significant problems for many Windows developers,
and since most active maintainers are currently included in that group,
the plugins have been deemed more trouble than they are worth.

* Fix displaying checkboxes within Grid editor row.

- Checkbox margins should match regular row content margins.
- Multiselect checkbox label should only be visible for assistive
devices.

https://github.com/vaadin/framework/pull/12043 changed resync message sending to be deferred to queue. Now also the setting of the semaphor in message handler needs to be deferred to its right place. Otherwise there is possibility for a timing glitch. I.e. MessageHandler is set to resync handling mode before message is actually send.

Fixes: https://github.com/vaadin/framework/issues/12151

* Fix to LayoutManager size calculations during transform.

- ComputedStyle is slower but more reliable than using
getBoundingClientRect, which does not work as expected if a transform
has been applied to the element or one of its parents. This is a problem
e.g. with PopupView, where getBoundingClientRect will return too small
size (or even zero size) for all the popup contents while the opening
animation is active. ComputedStyle ignores the transform and returns the
expected value.
- The presence of the element in DOM must be checked before the size is
requested from ComputedStyle, if the element has disappeared from DOM
without a warning and calculation is attempted anyway, the browser gets
stuck.
- Possibility to configure LayoutManager to use the less reliable
calculations for applications where the slight performance difference is
more important than layout issues within elements that have transform
animations.
- Manual test, problem isn't reproducible by TestBench.

- ScrollbarBundle: removed delays in scroll handling that were only
needed for IE8, added possibility to update offsetSize and scrollSize at
the same time in order to avoid triggering unnecessary scrollbar
visibility change events during the intermediate state.
- ColumnConfigurator: added new method that allows setting column widths
without triggering element size recalculations.
- EscalatorProxy: added implementation of the new method to
ColumnConfigurationProxy.
- Escalator: switched to use new methods in ScrollbarBundle and
ColumnConfigurator, added a pixel to a scrollbar offsetSize calculation
that was for some reason consistently one pixel too low, removed
duplicate method calls from sectionHeightCalculated handling as those
are already handled by the calling method and can cause incorrect
intermediate state and unnecessary scrollbar visibility change events,
added implementation of the new method to ColumnConfigurationImpl with
the element size recalculations made optional.
- Grid: updated column minimum width calculations to take into account
the potential presence of a resize handle, updated expand ratio handling
to not trigger element size recalculations until the entire handling is
finished.
- Test for column width handling when there are multiple columns with
setMinimumWidthFromContent(false)

Fixes #12139

Use generated IDs for MenuItems when an ID is set for MenuBar. Tying the ID to MenuBar's ID helps with the possible case of having multiple MenuBars on the same view and avoids to have excess id's when not needed.

Fixes: https://github.com/vaadin/framework/issues/8186

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.

* 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

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.

In Firefox and IE11, the 'Create Link' button of the RichTextArea (RTA) only works by turning some highlighted text into a link (by adding the inserted URI as the href property of the text). In that, the RTA in these two browsers behave similarly to the way it does in Chrome and Edge. However, in Firefox and IE11, clicking the 'Create Link' button has no effect if no text is pre-selected by the user. This is different from the button's behavior in Chrome and Edge where the user's provided URI is inserted, both, as the displayed text and its href property if no text is highlighted.

This fix enables the RTA's 'Create Link' button to work consistently across the supported browsers. Specifically, (and in addition to enabling adding the href property of a highlighted text), this fix enables Firefox and IE11 to also insert a new Uri as a text and its href property if no text is already highlighted.

The previous patch https://github.com/vaadin/framework/pull/11951 did fix the problem (frozen column indicator wrongly positioned)  it was meant to, but caused a regression in hiding / un-hiding. 

This new fix addresses both problems, i.e. it applies multiselect column compensation in other way, without causing problem in hiding / un-hiding logic

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

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.

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

* 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.

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.
