Block inserter switches itself to paragraph block, when the user modifies any block settings before inserting the block.

[alanjacobmathew]

V: 5.8-RC1 . Theme: Twenty Twenty One . No plugins installed.

The issue also exists in the stable 5.7.2 version. Tried with Twenty Twenty and Astra theme

To reproduce:

1: Add a new post.
2: Click on Add Block
3: Modify any of the block setting in the toolbar on the right.
4: Try to add that block again. I can't insert just any block, unless I just want to transform it to a heading block or something similar.

I am not sure whether this is a bug or a feature, but if in case it is a feature the 'text' in the block should be changed, as the user can't add anymore blocks in there.

Thanks @alanjacobmathew,

I've ​opened an issue upstream on the Gutenberg repository as this will need to be fixed there.
