The values in the mass matrix is related to the "real" area/volume of the elements. If the simulation domain is small (with domain size X etc. smaller than 1e-6), the element areas/volumes are dipping below a threshold designed to keep them from blowing up when I take its inverse.

That threshold should depend on the size of the domain.
