Wrong firstResponder ordering on simulator

When we click the street cell. If I press "tab" it would go from street -> city
instead of street -> postal.

this only happens in the simulator since it have access to the "tab" key as keyboard.

I'm assuming it would behave the same way if an iphone/ipad is connected to wireless keyboard and press tab
