Bar selection slider on scale histogram widget snaps back

[makella]

What is happening?

Selecting any bar (other than the first one) or a range of bars, causes the selection bar to snap back one or more bars (in most cases). I'm not sure how to explain it working in my gif below when selecting the last two bars... in other tests, that was snapping back too:

What should happen?
Should be able to select one or range of bars without snapping.

Steps to Reproduce
See gif above.
