Can you also remove all these AnimateNow()s that were added to make the checks
not explode? Maybe once the blink side is fixed?

I talked to loislo about this and am going to conservatively wait and remove it

actually fix the flakiness even if the approach wasn't great, rather than
changing to an untested solution #2 really quickly.
