(stable) When cancelling an edit of an inline with content, don't hide the inline
Summary: See PHI1753. This condition got rewritten for suggested edits and accidentally inverted.
- Create a comment, type text, save draft, edit comment, cancel.
- Before: comment hides itself.
- After: comment properly cancels into pre-edit draft state.
