Min/max control broken during Zelda merge

[JohnONolan]

The min/max control (bottom left corner of nav menu) broke during the Zelda merge, I'm not sure why. This needs to either be fixed or replaced by the Ember version which @acburdine was working on

My PR fixes it and works as it should.

@john As far as I can see it's working on master. I have caching disabled and just rebuilt all assets so I think it should be ok.

It works intermittently for me in master - it seems to require a refresh to kick in after signin, will look at @acburdine's PR in a sec ;)

Ah, that makes sense as those elements that are getting event handlers bound to them won't exist when didInsertElement fires and you're not authenticated, and the only time it will re-fire is if the application is reloaded.
