Reviewed by Simon Fraser.

Neither of these tests should change behaviour with interop, but we can fix them at the same
time.

This adds a new subtest check for hitting the parent box3 element in the area where it's
drawn on top of the child. We're currently failing this, as we hit-test box4 despite it
being rendered behind.

* LayoutTests/transforms/3d/preserve-3d-not-applied-to-ancestors-expected.txt: Added.
* LayoutTests/transforms/3d/preserve-3d-not-applied-to-ancestors.html: Added.

This test has a transformed ancestor of the preserve-3d element, which shouldn't be
participating in transform accumulation (and rendering already shows that it isn't).
The bounding client rect should match, and it currently doesn't.
