Merge https://chromium.googlesource.com/chromium/blink/+/d050f9be579d02e40c8924b4153376bc32ffba1a When a child element is positioned very far away the width/height of layout overflow rectangle may overflow. The patch detects such cases in RenderOverflow::addLayoutOverflow and shift the top/left edges of the rectangle to avoid overflow.

Created attachment 211084 [details] Just adds the test I couldn't make the test to fail. We can just add the test for now and merge the code change later if the test started failing.
