Comment (by westonruter):

 @celloexpressions @curdin please review my additional changes in
 [attachment:36678.3.diff]. I was able to simplify it by tying everything
 into the `paneVisible` state, setting its state value and listening to
 changes to the state value to cause the UI to change. By listening to
 changes on the `paneVisible` state value, this also allowed for the
 elimination of the separate `paneVisible` event. I also fixed an issue
 with the `aria-expanded` and `aria-label` attributes not getting updated.
