Yes, that's surely always worked.

My point is specifically that it didn't seem to work when the client cert
file includes an intermediate CA cert, but not a full path to a trusted
root cert. (Note that anything in the server's root.crt file is a trusted
root cert so far as the server is concerned --- it doesn't matter if it's
a child of some other CA.)

Yes, we were already explaining that in the existing docs.
