Problem is that we update the layout viewport when the visual viewport is empty, for subframes:

FrameView 0x121bf0b80 updateLayoutViewport()
layoutViewport: (0,0) width=0 height=0
visualViewport: (0,0) width=500 height=300
scroll positions: min: (0,0) max: (0,0)
layoutViewport changed to (500,300) width=0 height=0
