Kneejerk reaction: no, it shouldn't, because the contents of the shadow DOM should be hidden by default.

(And yes, iframes totally work inside shadow DOM, why wouldn't they?)

Yeah, I agree it shouldn't, but per specs... well, not sure, because
iframe handling in shadow DOM isn't really spec'ed.

(iframes shouldn't per current specs work in shadow DOM.

Afaik everyone agrees they they should work,
but there are several spec bugs to fix.
Like this and bug 27325 and bug 26365)
