STR:
1. visit https://twitter.com/fabricedesre/status/979899223419240449
2. move the mouse around the twitter feed
3. notice how the profile bar often suddenly moves in front of the thread content in a very surprising and awkward fashion
4. try to scroll up the page
5. notice how the profile bar goes back to where it's supposed to and the thread reappears
I wasn't able to reproduce this in a mozregression session using a clone of my main profile, and I couldn't reproduce this after updating to the latest 3/30 nightly :/

mozregression points the finger at bug 1448841. My STR are to visit facebook.com and move the move rapidly between the left menu and the main feed content. The menu at the top of the page will flicker in and out of existence.
