ST stopped sending mouse drag events after any ButtonRelease event was
received. For example if you were dragging and then scrolled the mouse,
the dragging events stopped.
Fixed this by locking the dragging button to the first button pressed.
ST will keep sending drag events for that button until that button is
released.
