List View: Allow Escape key to deselect blocks if blocks are selected (…
Browse files Browse the repository at this point in the history 
…#48708)

* List View: Allow Escape key to deselect blocks if blocks are selected

* Add comment, check which tab is active in post editor

* Add speak call, use clearSelectedBlock action

* Add behaviour to widgets editor, too

* Move clear selection handling down to the List View container so that if focus is on the close or tab buttons, Escape closes the list view instead of clearing

* Try selecting the last selected block when closing the list view if no blocks are selected

* Revert changes

* Try clearing the selection from within the list view

* Revert change

* Add test

* Fix issue where announcement for deselection was not occurring
