Right now when you select/highlight the text with your mouse in a popup or dropdown menu and the mouse goes out of the box, the popup/dropdown menu closes. That is because it is triggering the close popup when the mouse click goes up. Instead, it would be nice to trigger it on mouse down, so right when someone clicks outside the popup, it will close it, and when someone highlights the text in a popup and accidentally moves the mouse outside of the popup, it won't close it.
