Because the biasing is in reverse junction, and the current source is ideal, so it'll keep increasing the voltage, in order to get the necessary current through the junction. It's like feeding current to a diode in reverse junction. Reverse the current source direction and you'll see it stabilise, because it's forward biased

In practice if the reverse biased current of a base emitter is very much in excess of the minority charge carrier current than that junction will break down due to avalanche effect and destroy the transistor
