We should consider implementing -webkit-tap-highlight-color (and if so, get it added to compat.spec.whatwg.org). It's the third most used unimplemented CSS property, from the data I've seen.

According to Fenix folks, the current grey highlight is handled here: https://searchfox.org/mozilla-central/rev/8b7aa8af652f87d39349067a5bc9c0256bf6dedc/mobile/android/themes/geckoview/content.css#269-279

We should check how many of the uses are transparent or such. For example, bootstrap contains as its first rule:

html {
  -webkit-text-size-adjust: 100%;
  -webkit-tap-highlight-color: rgba(0, 0, 0, 0);
}

That means "disable text-size-adjust, disable tap-highlight-color".

This is part of the problem with the current shape of the telemetry we have, for this stuff, FWIW...
