Looks like just a tiny bit of fuzz along the edge of some of the characters.

The frequency here seems to have gone up a lot since bug 1169331, for which I had to fuzz lots of other Android reftests. Nobody knows what causes these failures, and given bug 1156817 and the complexity of setting up a local Android reftest debugging environment, we decided it wouldn't be worth spending time figuring this out until bug 1156817 has been fixed.

I'll add a fuzzy-if annotation for this test on my next push to inbound.
