I don't think we're expecting srcdoc to be the common case for <iframe>,
are we?

FWIW I agree these are niche features and I agree with Ian that adding
another case where the simple implementation is broken is OK.

I suspect the main use-case for "Show only this frame" and "open frame in
new window" are on sites that are wrapping portals around other sites, and
those are rare and won't be using srcdoc. "View frame source" is useful for
Web developers and should probably be updated to show the srcdoc text from
the parent <iframe> if the URL is about:srcdoc.
