Integration Component Coupling in Infinite Element Domain

I'm using an Infinite Element Domain to simulate time-dependent diffusive mass transfer into an "unbounded" space. The solution has converged and looks believable.

I would like to calculate the total mass transfer into the space at various time points. I have tried to do this by integrating concentration over the simulation domain using the Integration Component Coupling. However, this method of integration seems to spatially integrate over the geometric domain as drawn rather than the scaled infinite element domain, which produces a result less than the correct value. (Alternatively: If I integrate an integrand of 1 over the infinite element domain, the resulting volume equals the volume of the drawn geometry rather than the volume of the scaled infinite element domain.)

How do I spatially integrate in the scaled coordinate system of the infinite element domain?
