Description
Monitoring performance of the player I noticed a long task towards the beginning of the loading that is caused by `loadPlayers()`, which ends up calling several `appendChild()`s.
This is most likely called by the fact we don't batch these DOM mutations in a `vsync` / `resources` `.mutateElement()`.
