Yes.

I suspect it's the removal of the updateLayout() call from setIsActive(), that
just happened to be at right place at the right time to ensure that everything
is set up for scroll-to-reveal to do its thing. Without it, some of the
dimensions are (0, 0) which messes up the scrolling. Even prior to r20901,
opening the test in a background tab, for example, would make it fail.

I've readded an updateLayout() back in order to test my theory. If it's right,
then that call should probably be added in a more appropriate place to ensure
that scroll-to-reveal has all the information it needs.
