@iseulde any idea about this. I feel I saw something related to this recently in one of your PRs.

We've never had any logic for this in the image block I think. I'll have a look.

What should the behaviour here be? Should we break out only when the caret is at the end and enter is pressed twice? Or should this only happen in the middle of the text?
