In my answer to Is it possible for many domain names to share one IP address? I wanted to include a link to the IP for superuser.com to show how shared hosting and accessing by IP's did not work, however when I attempted to add a link to 198.252.206.16 it circled the box in red and put the popup window on the right.

I totally missed the popup window when trying to figure out why it was erroring out. In fact I was typing this up as a bug report (for not showing any message at all) and I did not spot the box until I reproduced the issue and was taking the screenshot.

The red error text below the message box was much more visible then this new popup and I feel that it should be switched back.
