As discussed in person, this prevents the creation of windows in a lot more cases than just "popups".

The check(s) should be moved to everywhere we already consult the existing popup blocker. i.e. calls to allowPopUp()

Do we also need to consult the content extension before popping out to another app (say, from an itms:// link or some other custom scheme link)?

I think popping out to another app is very similar to popping out to another window.

Probably.  Where should this code be, and where are tests that test something similar?

Used Document::completeURL with proper null checks instead of URL(ParsedURLStringTag, const String&) like is done elsewhere in DOMWindow::open
