I've noticed that when selecting two items (faces, points, edges) in Measure it's not possible to move the numbered squares that label each selection; if I zoom or pan, they re-snap to the same location relative to the selected items. This usually isn't a problem but for small components, e.g. the ball (selection 2) in the attached screenshot, it can be quite annoying since the label covers most of the item, as well as the arrow showing me where the measurement is snapping to.
