// Testing that sendKeyFrameRequest actually results in the sending of keyframe
// requests is effectively impossible, because there is no API to expose the
// reception of a keyframe request, keyframes are sent regularly anyway, and
// the spec allows the receiver to ignore these calls if sending a keyframe
// request is 'not deemed appropriate'! sendKeyFrameRequest is at most a
// suggestion.
