It looks like this type of problem happens when we try to crop past the bounds of the image? This test has a slightly larger crop size (400, 400), so maybe it's wider than the android screen?

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/71f45e21cf7f65aa80389531cdd7c9bfc87f0739

commit 71f45e21cf7f65aa80389531cdd7c9bfc87f0739

Rework Pixel.2DCanvasWebGL to be less than 400px wide.

The test was experiencing the error "Invalid dimensions" on some Android
devices. It's probably because the test was trying to do a screen capture wider
than the dimensions of the phone.
