Reverts #28551

Looks like this is causing an issue for multi-size creatives :\.

The plan should be to revert the change here to status quo. After that, I will make a code change to apply centering logic to multi-size creatives only, and then we can re-apply the reverted CL.

Alternatively we can unlaunch only the experiment traffic fractions, and then roll-forward a fix (applying the centering logic to multi-size creatives).

Make sense. I am curiously how it can be caught so quick? Did someone from gq
complained?

@keithwrightbos spotted it by coincidence earlier today.

I specifically tested for this case, but must've missed it. I think on the page that I tested, the slot was already centered, so I must've not noticed that the (smaller) creative was slightly off center.

@glevitzky I think we can simply do a fix forward. I don't think the experiment will give us more helpful insights, because the failure should have been caught but was not.

Reason I want the experiment back is that it will prevent the bug from going out to 95% of traffic. Agreed that it won't give us any new info, though. My thinking is:

  1. Revert PR so that we can prevent uncentered multi-size creatives from appearing on (most) live traffic.
  2. Add code change to apply centering to (only) multi-size creatives < than the slot.
  3. Wait for (2) to go live.
  4. Remove experiment flag.

If we don't do (1) first, and go straight to (2), then we'll "break" multi-size creatives until the next code release.

@glevitzky Yeah I agree we must prevent it from getting out now. I was thinking your alternative approach is good enough.

Got it. I'll put together a separate PR, then.

wasn't this out in last week's release via a flag flip?
