Reviewed by Simon Fraser.

With UI-side compositing, the two JS functions in the test are combined in one
updateRendering(). So we report one repaint rect which the entire canvas rect.
There is no user problem here but the test does not generate exactly the expected
output.

The fix is to make the first JS function run in the first updateRendering() loop
instead of running it onload. To fix the test for WK1, two requestAnimationFrame()
need to be scheduled before runing the first JS function.
