Somehow Ace's "changeSelection" event is triggered when hitting backspace (and shouldn't!). changeSelection on our side triggers enough work to make the holding backspace sluggish and laggy. This fix ignores selection with a length of 1, avoiding mutating the state altogether when hitting/holding backspace.
