/* This test does not always exercise the bug it was written for, in the sense

   that the test would fail without the corresponding patch. It seems as though

   when hitting bug 1743602 the test does not exercise the bug. If bug 1743602

   gets fixed hopefully this test will end up exercising the bug. A dev pixel

   ratio of 1 seems to make it hard (but not impossible) for the test to

   exercise the bug. This is what you get when running the emulator locally or

   in our CI infrastructure. A dev pixel ratio of ~2.6 (23 appunits = 1 dev

   pixel) seems to make it easier (but not 100%) for the test to exercise the

   bug. This is what I got when running the test on a real phone locally (pixel 2).
