Where does 馬が合う come from?

The Daijisen (via Kotobank) defines it as getting along well and hitting it off, with no origin note, and English Wiktionary breaks it down as “the horse(s) match”. A common explanation is that a rider and horse who suit each other move as one, but no dictionary confirms it, so treat it as a theory.
