Restricted editing boundary can be crossed with a command which operates on more than the current selection

There are two commands that come to my mind:

• unlinking
• delete word

Content that will break:

Reported by @oleq:

1. Go to restricted mode
2. Put the caret at the beginning of an editable (exception) area
3. Click “Link”
4. The link is inserted before the exception (the exception should be included)

type some link and save.

Another case (Firefox, native spell check):

The native spell check did not fix "computter" when the action was performed on the part outside the exception. When performed on part in exception we get word changed outside the marker.

Words on Chrome are treted separately if divided by <span> (marker). I was unable to fix a word outside the exception marker.

And also Safari does weird things with fixed words:

1. put selection at the end of an exception marker
2. write " cooool"
3. press space
4. the word get fixed to cool but "l" is out of the exception marker
