sad that we don't have a comparable enum and use integer degrees instead, but not your fault

This (and possibly those above) needs to check isValid, I think? (what happens if the WebProcess is dead when we get a UIWindowDidRotateNotification?)

This is peculiar. It iterates starting with this frame, but continues up to this frames siblings and parents if the frame is not the main frame. I think this function is meant to be called only on the main frame, so if we do want it on the frame, then it should be on the MainFrame class.

But actually we try to avoid putting these directly into Frame these days, so normally we’d put this into something like EventHandler.

This is old fashioned. Here’s the modern way to write it:

    for (auto& frame : frames) {
        if (Document* document = frame->document())
            document->dispatchWindowEvent(Event::create(eventNames().orientationchangeEvent, false, false));
    }
