This.

Font scaling itself is nonlinear enough, but the way margins scale with font size is downright psychotic (enough so, that I’d advocate for redoing it with a useOldMarginBehavior property that can be set.).  Changing margin size can change what size font fits in the wrong direction, or by more points than the change, or . . .

But the approach of an initial mathematical computation , followed by the iterations—which must happen in both directions unless a hit is made.
