[49/132] tiled-drawing/scrolling/frames/coordinated-frame-lose-scrolling-ancestor.html failed unexpectedly (text diff)
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</pre>
