I'm getting an issue when playing from the SERP. If I go to the videos vertical it doesn't trigger the video and it things it's playing from youtube. I assume this is a breaking bug so marking as "request changes".

No, you've found a bug, and I am not able to repro. I think the intermediate visit to Images is causing the refferer to be setup incorrectly.

We can do two things:

Merge this PR as is and open a follow up task. (This is not gonna be merged to main)
Close the PR to prevent from blocking upcoming one with more pixel changes, and re-test pixels in the next one.

WDYT?

Closing as upcoming PR includes a fix. I'll add pixel test instructions there
