Notes

The shortcut Primary + A twice will trigger multiSelect between the first and the last block in getBlockOrder() a selector in the block editor store which accepts an optional rootClientId "of the block list for which the order should be returned, defaulting to the top-level block order".

It feels like the getBlockOrder selector should either default to parent as rootClientId or we should rebind the select all shortcut in the widgets editor.

Looks like this would also be fixed/improved by #31859, though it would still be possible to select widget areas.

Assigning @talldan because IIRC he's taking over #30462.
