That is an interesting concept. Is it described in a different spec? I think our tries load the fragment into the same document. Which would be harder to detect. But we still don't support external resources like clipPath mask or paint servers yet.

Mask does not affect hit testing, but clipPath does (the only resource). But it does not expose this region without the interaction of the user (move mouse over clipped region). That is different with the scenario that Adam described, which can be fully automated.
