Reverse engineering the UJS code wont work. Every time an update happens the minimised, obscuricated JS code gets different variable names to the previous update. And the scope of everything UJS-related is closed - the window can access basically nothing.
600 votes is highly unreasonable, it's a feature which used to exist and is a usability feature.
It's annoying when it auto zooms in a similar way how the last army deployment changes to attack/transfer. It changes the flow and because of that its counter-productive.
I'll stick this here
