For the User Testing builds, we want to make sure the versions of the experiment that go to History (currently the main branch and the T265674 branch show a momentary highlight on the appropriate cells (a single cell will highlight when tapping from a large event, multiple cells may highlight when tapping an "x small changes" link) when the user lands on the screen.

TBD on color specifics and timing, maybe that can be figured out synchronously with @cmadeo .
