Having the ability to edit a Reusable Block in a post is interesting, BUT with over 40 contributors and over 600 core contributors how is it possible that NOBODY has figured out that if anyone who is not an Administrator or Editor, when editing a post that contains Reusable Blocks and clicks on a Reusable Block, they will crash the entire post with just that one click?

My answer to this would be for those who are not allowed to edit a Reusable Block (only Admins and Editors can edit them), the RU Blocks to be locked in posts and pages and not editable, just like they were a few versions before.

Also, are the accordions in the Block Inserter ever coming back, or we the peasants do not deserve to have nice things anymore?
