[Bug 25412] Allow some recursion in NodeIterator/TreeWalker

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

--- Comment #42 from Aryeh Gregor <ayg@aryeh.name> ---
I don't know why anyone would actually want to use recursion here.  Unless
someone has a use-case, I just want something standardized that requires as
little implementation change as possible to get interop, so that when pages do
weird stuff they'll be identically weird in all browsers.  I don't care if the
recursion actually does anything useful.  3/4 of engines do allow some type of
recursion, and it's slightly simpler to spec, so I don't think we should go out
of our way to prohibit it.  If WebKit and Chrome agree, I'd go with them,
unless Edge's behavior is more useful for something.
