It looks great, happy to approve. Just a non-blocking question - when this A/B test is live, does the web send all Ophan events with this A/B test participation? Or just the events that involve default videos?

What does this change?
Adds a 0% server side AB test to test click-to-play default videos vs autoplay default videos.
Test behaviour
Control: mimics the existing on-site behaviour (i.e. longform videos will autoplay by default). Note that this behaviour can be overridden by reduced motion and autoplay settings to turn off autoplay.
Variant: all longform videos will be click to play by default. This behaviour cannot be overridden.
This test will only be measuring the impact on fronts as the existing behaviour of long form videos in articles is already click to play by default.
Why?
Currently, default videos on the front are always autoplaying. We would like to understand the impact of the two user experiences in regards to video and page engagement.
