Remove event listener that drew cue

-After correcting the delay on 'afterexpand' and 'aftercollapse' events I realized a problem that was being masked by the incorrect delay. This commit seems to fix it, as the 'select unselect' event listener does the job of drawing and clearing the visual cue just fine.

- This commit may be problematic or cause side effects, but doesn't seem to currently be a problem. Can be safely reverted back if that is the case, but that will still leave a problem to be fixed, that is, when animations are disabled, the cue is drawn on the screen too fast and is redrawn at the end of the animation by the 'select unselect' listener anyways.
