We rely on AppKit-internal events to know when a window is being
dragged. In Catalina, AppKit stopped sending the "drag ended" event when
no drag actually took place, though it still sends "drag started" events
when the title bar is clicked. Ironically, this caused us to think the
window was still being dragged. In that case, waiting for the mouse
button to come back up should allow us to determine when the drag should
end.
