[Bug 25412] Allow some recursion in NodeIterator/TreeWalker

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25412

--- Comment #46 from Aryeh Gregor <ayg@aryeh.name> ---
We should be able to add usage counting to Gecko, but I don't know how
interesting it will be.  Currently we throw in this case, and have thrown for
years, and have never received any complaints that I know of, so we already
know that the behavior is web-compatible for us.  If you're concerned that you
might go down different code paths than Gecko, you'll have to add usage
counting yourself.  (This doesn't strike me as plausible in this case, but the
web is a very strange place!)
