Vincent Massol: Sorry for the late reply, this Jira somehow didn't notify my about you comments, even though I'm reporter and listed as watcher.

I need to debug if it's just a misconfiguration in my user profile here, or a problem with my mail server, or a problem with the notification mails from this Jira.

What markup do you mean exactly by "original markup"? The Xwiki page before editing at all? Or the markup from the copy source? This was just a random website I randomly chose for testing.

The Xwiki page was empty before I started this editing demo. So not quite sure what I could provide here.
