Thanks for that suggestion; it wasn’t the answer, but it did lead me to rewrite significant portions of my code and the whole is a lot better for it. I finally stumbled across the answer by accident (one for the archives, this): In IB, the textview had the ‘non-contiguous Layout’ option checked. According to the docs[1], this is supposed to be off by default for reasons which exactly apply to my situation, but I note that if you build a new project in Xcode 9 and just throw in a bog-standard NSTextView, that option comes along already checked. 1.
