issue where stepper is in tableViewCell and tableView and press on +/- while scrolling and autorepeat is true

[dawid]

so here is the attached gif of the bug:

basically happens when one presses +/- when the tableview is scrolling, it causes never ending acton (-- or ++ on the value). when one tries to to decrease while in never ending increment, it resists (as seen towards the end of the gif) and just continues to increment.

gonna do a PR.
