Not quite sure here, according to #85792 multires should be able to find solution for n-gon or triangle base topology. Mesh could be subdivided by un-subdivide operator though. It doesn't subdivide uniformly though.

@JosephEagar Do you know if this is a bug?

I'll tag this as a known issue at this point. This should be addressed with further work on the multires modifier
