Close tab on mouse-up event

[WildOrangutan]

It seems like tab is closed, when you click "x" icon, immediately on "mouse down" event. I think it would be better to close it on "mouse up".

Sometimes you can click something on accident, or you change your mind after you click. In that case, I usually hold left mouse button pressed and drag it out of "x" icon, and release it somewhere else.
