* Increase sleep time for test failing in validation
* Merge branch 'master' into fix-11517
All components are now in immediate mode by default.
V7 compatibility components will use AbstractLegacyComponent that has immediate.
V7 ColorPickerPopup will not have setImmediate, since it extends V8 Window,
which is not in V7 compatibility packages.
Removed OutOfSync and ResynchronizeAfterAsyncRemoval Tests,
since those tested UI in not immediate mode, which is invalid now.
Removed WindowResizeListener, LazyWindowResize, test UIs,
since both used immediate and there were no test run for either.

Flush the active connector before executing a shortcut action
This change removes the old BeforeShortcutActionListener which was
introduced before ComponentConnector.flush() to resolve the same problem.
