Comment 6 for bug 553263

I'm not a programmer myself - just helping with bug triage. I set it to Wishlist following your initial description as "suboptimal" behavior and because it doesn't prevent to adjust/set the value for the spin box. But I confirm it is a usability issue and also happens when using the scroll wheel to adjust the spinbutton values.

(Possibly related: entries in the undo history for each step even if the spinbox value isn't updated?)
