Hi, after update to wordpress 5.7 i have notice that reusable block created with generateblocks (button block) went unusable. When i try to edit block the contextual menu dissapear as soon as try to hover cursor on it.
Attach short screenscast.
I have same behaviour on 4 sites.
I have tried many thing including :
Go to single reusalbe block post and re-save it
Save post that contain reusable block
