ALWAYS_LOG(LOGIDENTIFIER)

You should add logging for each of these rejections, eg:

    ERROR_LOG(LOGIDENTIFIER, "The video element is not ready to enter the Picture-in-Picture mode")

 The string in the Promise rejection is available to script, but the runtime logging will show up in the console log so we can diagnose failures later.

This should be a Ref<const Logger>

Cannot use ALWAYS_LOG() here because this function is static.

Right, will fix it.

  This was not changed in the final patch.

Right. We cannot use macros like ERROR_LOG because the function is static.
