Fieldset Locked Up the Entire Window

[Prestar]

I was editing a Topic in a new game I'm looking to put together, and had pulled a bunch of information, and edited it, from the other MW Site, when I went to put a third Fieldset into the topic and it locked everything except scrolling up in that tab.

 

I've refreshed the entire page, reloaded it, and taken the "Exit" dialogue Chrome gives me all at least three times each by now, to no change.

And god love it, Baldr is refusing all methods I know of uploading photos, because I otherwise have a nice collection of screenshots of the issue.

After troubleshooting, we tracked this down to some weird HTML in the source post on OGMW.
