Animated GIFs cause entire window to redraw

Details
To see the problem, build with double buffering turned off (nsViewManager.cpp).
Go to a page with animated GIFs (see URL). Note that whenever an animated
GIF is updated, the entire window gets redrawn (toolbars and all).
In builds with double buffering, this problem will show up as a general
slowdown (and increase in CPU usage) on pages with animated GIFs).
(Only tested on Mac, though likely to affect all platforms.)

The reason animated GIFs cause contant redraws is explained in bug 3853; every
time the status message changes, reflow and repaint happen. And animated GIFs
cause continual status message changes.
since this bug may nicely provoking bug 3853 into existence, we should try and
fix problems associated with 3853 before fixing this image lib thing.

Bug 3853 has apparently been fixed. This problem still exists in today's build.
