Description
Here is a demonstration using the tempo control:
The following events happen in the gif:
1. When two fingers are placed first on the trackpad (the beginning of the wheel scroll motion) the tempo drops from 140 to 138;
2. After a pause, the normal scrolling action changes the tempo to 128;
3. The fingers are then lifted off the trackpad and the tempo mistakenly changes to 126.
More details on cause and suggested solution to follow.

Research direction
Reproduce the trackpad two-finger wheel-scroll sequence on the tempo control and observe the LCD widget behavior. Start by tracing the tempo control's wheel-scroll handling, including the event generated when fingers are lifted. Done means normal scrolling still changes the tempo, but ending the gesture does not reduce it again.
