I haven't looked at that literature myself, but I would be surprised if it completely disarms my point.

It's very believable that intelligence and height correlate, but the question then becomes "Do we overweight height in decision making, relative to its predictive power for success/intelligence?" If height very weakly predicts increased intelligence and we weight it strongly, that's still far from optimal decision making.

The correlation with intelligence isn't even necessary to ask that question. Hiring taller people also has upside in that other people (eg, your customers!) are biased toward them as well. However, and I admit this is conjecture, I still suspect allowing your own biases to influence decision making is a net negative.
