When you press mouse on ScrollBar's inc/dec button or its track, a timeline is started, in the time 0 it moves the bar, waits for some time, and then it repeats until it is stopped by mouse release. If you manage to release the mouse before the first keyframe is processed, nothing happens. This is very easy to achieve on touch screen - almost no tap works there. The first step needs to be done regardless of the length of the click.
