When e10s is enabled and the current tab is loading, switching to another tab causes the content area to turn black until the loading is completed, up to about three seconds.

This is most easily reproduced by loading two tabs, one with https://www.gmail.com, one with http://planet.mozilla.org. With both tabs loaded and the latter active, refresh Planet Mozilla, and then quickly switch to the GMail tab.
