REVISION SUMMARY
  According to documentation [1] `targetOrigin` is a required argument. Apparently it has to be "*" for messaging to an extension. Neither Firefox, nor Chrome cared about the lack of this argument but Waterfox (which we don't officially support and I didn't even know existed) complains.

  BUG: 411423

TEST PLAN
  - Waterfox has working YouTube controls now
  - Firefox and Chrome behave unchanged
  
  (I'm not going to do an "emergency release" as Waterfox isn't officially supported by us)

REPOSITORY
  R856 Plasma Browser Integration
