Ojan Vafai a0c612c89b Fix hit-testing of elements with the same z-index.
hit-testing needs to walk in backwards order from paint.
The previous attempt at reverse sorting by z-index didn't
reverse things with the same z-index. Instead, forward
sort the same way as we do with paint and then reverse
the whole vector.
