[Bug 21976] [imports]: Preventing DOM hierarchy cycles

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21976

--- Comment #6 from Anne <annevk@annevk.nl> ---
Right. My question is why do we allow those DocumentFragment pieces to be
identical structures? That's not how CSS @import works, or <iframe>, ...


Now, assuming there's a good reason. We'd need to allow a list of hosts for
DocumentFragment. And then expand the definition of host-including inclusive
ancestor to thus:

"An object /A/ is a host-including inclusive ancestor of an object /B/ if
either /A/ is an inclusive ancestor of /B/, or if /B/'s root has one or more
associated hosts and /A/ is a host-including inclusive ancestor of one of /B/'s
root's hosts."

Right?
