+/* 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).
