This pull request seeks to resolve an issue where reusable blocks are keyboard navigable when not intended to be editable. The previous implementation used a
pointer-events: none
style to prevent a user from interacting with the reusable block, but it was easy to navigate into with keyboard thanks toWritingFlow
behaviors.The implementation here introduces a new reusable
Disabled
component which intends to manage all field disabling automatically.Refer to included README
Testing instructions:
Verify that you cannot edit a Reusable Block until selecting the parent block and choosing Edit, including when navigating between blocks using the keyboard.
