[X] I have checked "open" AND "closed" issues and this is not a duplicate
Description
After entering "h1" after the "/", if you press backspace to change it to "h2," it doesn't work correctly. The same issue occurs if I enter "heading1" and then backspace to change it to another block; the action menu doesn't render properly.
Has this bug been raised before?
