This was due to the SVG generator finding a max dimension of 0 in one direction for scaling because a line and only has length and no height. Using SVG for the 2D preview was a work-around anyway, and now that the CadQuery subsystem does line discretization, a proper 2D preview with the line segments drawn manually can be created.
