That brought the cursor out of hiding, and the blank works as expected. Yay! But the formerly white blank (same as Subject:) is now colored, as you see. Did you intend that? (It's actually fine with me that way; just thought I'd ask.)
You used a version of the userChrome I have discarded and replaced, but I'll fix that in a jiffy. (I had to fix the "hover-order" problem and change a color or two, but I'll integrate yours with my revised one.)
