--- Comment #3 from Jordan Milne <w3bugzilla@saynotolinux.com> ---
We should add a caveat that the hit testing function should not descend into
subdocuments. 

The naive solution is to use the same hit testing function used for detecting
which element should receive a click, but descending into cross-origin frames
will leak information about the frame's contents via timing information. At
least Firefox[0] and IE11 were affected by this.
