The case I was particularly concerned about was not "presented" vs "not presented", but "has its own global scripting context" and "is neutral to script". A document in an IFRAME has its own Window -- if you have navigated away from that document, but still have a handle to it, does it execute <script> elements that you insert into it?
The current answer in Gecko seems to be "maybe, possibly depending on what else is going on". In particular, it may depend on whether the document got placed in back/forward cache, the exact Gecko version (there are some patches that may inadvertently affect this), etc. See https://bugzilla.mozilla.org/show_bug.cgi?id=293175 for more information on part of the issue...
I would say that ideally the answer here would be "no". -Boris
