If I enter some text into my TinyMCE editor and then press the fullscreen button, it opens up an empty fullscreen editor, deleting all of my content. I've confirmed that WYSIWYG Cleaner is causing this problem, but I'm not sure how.

Interestingly, if I start in the fullscreen editor, enter some text and then return to the normal editor, my text is preserved. Of course, if I press the fullscreen editor button again, the text is lost for good.
