Original issue's description:
> GestureRecognizerTest tests both Aura and Unified Gesture Detectors.
> 
> This is in preparation of landing the unified GR
> (see https://codereview.chromium.org/251543003/).
> 
> There are some cases where behavior differs in minor ways.
> 
> This is sometimes dealt with by increasing the test's margin of error
> (for instance, slop handling is slightly different, so we now
> exceed the slop more thoroughly).
> 
> This is sometimes dealt with by ignoring the test if the test is
> run with the unified GR.
