pass font-size changes to getHeightForWidth

This is a micro-optimization for laying out models whose height depends on the font-size of the responsive-content container, rather than on the model's own width. This is true of the sensor model, which has only controls in the model window, and it would be true of models that have a fundamentally 1D rather than 2D representation.
