While this is a reasonable change, it seems completely unrelated to this patch?

Oh yeah oops, I thought I changed more in DummyPageHolder. I can revert it if
you want but I think it's okay to sneak in.

     m_frame->setView(FrameView::create(m_frame.get(), initialViewSize));
     m_frame->view()->page()->frameHost().visualViewport().setSize(initialViewSize);
     m_frame->init();
