Details block: multiple issues with deleting the block and inner block

[annezazu]

In using GB 19.8 and GB 6.7.1, I noticed a wide range of issues with the details block including:

• Great difficulty deleting the overall details block even after selecting it.
• Deleting the inner block with the prompt "type / to add a hidden" block causes it to bounce outside of the bounds of the details block.
• After you delete the hidden block, you are then shown the normal prompt for adding a block.
• Difficulty selecting the text of the details block to delete the text

Overall, having used it 20 times in the last hour, it's very frustrating to work with 😅

Deleting the inner block with the prompt "type / to add a hidden" block causes it to bounce outside of the bounds of the details block.

This might be related to #66564, I notice the details block is in the text category.
