The intended scale adjustment is to zoom in/out centered on the cursor. The correct behavior happens when the zoom interval contains less time than the recording (i.e., zooming in more than 1x). The behavior seems suspicious when the overview is showing time beyond the actual interval of the recording (i.e., zoom < 1x) or when zoom >1x and the left or right edge of the zoom interval is touching the overview edge (that is, the horizontal scroll bar is flush left or flush right).
