Had this on my app and reproduced it on your demo in 3.7.6, Example 7 - Scroll View (Panel)
If you single click (no drag) on the scroll view collider but not an item in the scroll view you can get the scroll view to move to a position that isn't centered on a child. To reproduce on the demo, select the center on items tick, drag view to be at the leftmost entry and single click near the bottom of the draggable frame (but not on an item). The view scrolls to somewhere between the second and third item but doesn't center on either.
