this is used in places like custom tabs, does this change have no visual change
on the resting state of both the chrome omnibox as well as the CCT toolbar?

[Bernhard Bauer, 2016/07/21 13:10:03]

The CCT toolbar is unchanged. The padding for a regular tab is increased by 2dp,
but that's intended to make the padding 12dp everywhere. I've uploaded some
screenshots at https://imgur.com/a/uJglP.
