------- Additional Comments from Alexey Proskuryakov <ap at webkit.org>
This makes me think that we might need to import another large XPath test
suite. Unfortunately, the only ones I know are XSLT-based, and would require a
lot of work to adapt.

I've tried to think of other places where we need to restore the context, but I
don't see any.
