Give the odd chip to the player the rule says gets it

Quick Split tells the dealer a leftover chip goes "to the first player left of the button". The pot wizard, on the same tool, handed it to whoever the dealer happened to tick first. Two screens, same split, different answer. The wizard now orders the winners around the table from the button before the calculator shares the pot out, so the leftover lands where the instruction says it does. The calculator itself is unchanged — it already gave leftovers to the front of the list, it was just being handed the list in the order the checkboxes were clicked. It's pennies, but it's pennies in front of the person who didn't get them, and a dealer who has just read the other screen's instruction out loud looks wrong.
