Oh, I misread! The placement is working, then, and I'm a silly bean.
Remembering the placement is... gosh, that's a tough call. It's probably better the way you did it? The idea of it hopping around every time you reduce windows isn't super ideal, and the current issue really isn't that big a deal. I don't reduce windows much anyways. You probably made the right call, unless it's possible for the notes to conveniently "scale" their location, which is probably unreasonable.
