WebRTC card double-tap

I’ve just started using the WebRTC card to show RTSP streams, and have run into an odd inconsistency:

On desktop, if you double-CLICK the card, it expands to full screen (which is great).

But on Android, if you double-TAP the card, it flashes pause/ffwd/rwd buttons, and that’s it.

Any way to get a double-tap to behave the same as a double-click?
