Comment 4 by mcnee@chromium.org, Aug 7 

I don't currently have a device capable of running android layout tests, but note that from the bots, the test fails with the error: "Anchor point not in bounds".

Comment 5 by bokan@chromium.org, Aug 7 

This is likely the zoom out gesture using too large an increment, resulting in the initial finger positions being off screen. The tests were guarding against inaccuracies over long gestures so I'd rather avoid reducing the size of the pinch over all tests.

Could you add a check against the screen size and on a smaller screen use a smaller scale value.
