"Crosshair disabled" bug in portal

Disabling crosshairs in portal disables the crosshairs for first person vehicle views, which it shouldn't, assuming these crosshairs are meant to be in-world crosshairs on the monitors/heads up display of vehicles. This is a fairly weird thing especially on hardcore servers that don't have crosshairs, because it's unreasonable that a modern tank wouldn't have an aiming reticle.
