I haven't found this documented anywhere and I'm interested to know if
anyone can cast any light on it.

  By leveraging grab_set() when you kick off the drag and
  grab_release() when you wrap it up, you're golden - the

  events throughout the whole drag shindig, no matter how
  wonky the underlying system's event handling gets.
