Bug: Previous select is not closed when new one is opened via expand icon

[kot-pilot]

After researching source code I've found that select is using 'onGlobalMouseDown' callback for tracking outside 'mousedown' event to handle situations where outer click occured or another select instance is opened - then it closes all selects, which were opened before. Unfortunately it doesn't work for situation with opening next select through clicking on 'expandIcon' , because 'rc-select' component inner implementation is calling event.preventDefault which makes impossible to catch this and close previously opened select instances.

We're running into the same problem.
