Fixed Page freezes on clearing complex formatting

[CyberAP]

To reproduce:

• Open this thread and copy first post contents into your editor
• Select all the text and hit 'Remove formatting' button

Here is the text in case the thread above is lost:

Text gfdgdfgdfgsdfg gdfgd fgsg dfg dfgsdgf fg

Warning: The page actually freezes!

I've fixed this (not rolled out yet) and added a check to prevent an infinite loop if we have a bug in the future, but hopefully it won't come up!
