It's currently animating "height", which forces reflows of both the content window and the keyboard itself. One option to speed this up is to animate the keyboard slide-in with -moz-transform, and then set the height when the slide-in animation is finished. That will be maximum framerate and quite responsive. The expensive reflow is off the critical path.

We should follow up with UX about this too.
