transform-style:preserve-3d has incorrect hit-testing of negative z-index
::after.

Reviewed by Simon Fraser.
We call hitTestList with the intention of storing the result in the temporary
object 'hitLayer',
and only mutate the final result 'candidateLayer' if the depth test passes.
Unfortunately the 'result' variable is also part of the final output, and this
gets mutated
on hitTestList calls that don't pass the depth test.
This creates a temporary 'tempResult' (like we do for the other sections of
this function),
and only copies back to 'result' if the depth test passes.
