Comment(by was):
The fix for #12000 also works for this particular example. I really
hope that all other matrix types (now and in the future) respect this None
convention, since they will all have the same problem if we go with the
#12000 fix rather than the fix here. We could add documentation in the
file matrix/docs.py that reflects what should happen with None, and we
should try to add a test that things work with several different types.
