I recently came across a need to add a comment to a hyperlinked text while in Edit mode.

Steps to replicate:

1. Edit a Confluence document
2. While in edit mode, highlight a hyperlinked text (note: ONLY text that's hyperlinked)
3. Try adding a comment to it

Can you do it?  Because I can't.  The only way I was able to do this was to close or publish my page, highlight it, and add a comment outside of Edit mode.
