Bug when using two mouse connected

When using two mouse simultaneously
There is a bug in which the item sorting operation is not completed if an action of raising another mouse button occurs while arranging items by dragging one mouse.

A bit off topic, but how do you use two mice simultaneously? even outside of web, I've been curious about this for gaming purposes

Connect a different mouse to each of the two USB ports for use.

This could be fixed with #562, because we block dragging two items at same time from same group
