When including a URL to another thread in a post, the URL is automatically converted to the thread's actual page title. Like this...
http://www.flyertalk.com/forum/techn...xperience.html
If the post is then edited with Quick Edit, the URL reverts to the URL itself rather than the thread title.
Only using the Advanced editor will make it use the thread title.
I don't think that it used to behave this way a few months ago. Is this a new bug?
