Weird stuff happens if you drag some cards of an auto-pulling stack

Hi there,

First of all, thanks for porting this to a browser-based game. It's great to have an option to play it without having to boot into Shenzhen I/O.

Was playing just now and I got to the point of having 4 clean stacks of numbered cards. As the game was auto-pulling these stacks to the top-right corner piles for me, I clicked and dragged one of the stacks. It was going too fast for me to see exactly what happened, but I somehow got into a state where the 8 of one stack swapped with the 8 of another and then the 8 and 9 of the stack swapped places. This led to a state where the black 9 was on top of the black 8 (see screenshot below).

Not really a major bug IMO, but figured I'd point it out.
