QmediaPlayer won't setPlaybackRate() after pause() & play() if paused when slow

Application is playing a local file, am controlling the playback rate. I pause() the QmediaPlayer, and then resume with play(). If pause() is called when the playbackRate is set < 1, then subsequent calls to setPlaybackRate() after the video is playing have No Effect.

I can work-around by calling:
mediaPlayer->setPlaybackRate(1.0);
mediaPlayer->pause();

This allows me to set the playbackRate to some != 1 value after a call to play()
