For remote frames, we need to offset their hit tests by the scroll of their page.
However, in doing so, we inadvertently affected the main frame as well, which
doesn't need to account for the scroll offset. So, let's just apply this to non-
main frames.

My local simulator build wasn't able to run the test, but I've followed a follow
up to include a new test/infrastructure for this behavior:
