This is likely an upstream issue. It does not appear to be particularly active, but you could open a ticket here: ​https://github.com/kfl/mosml/issues I do not have macOS 15 to even try this.

I am unlikely to bother with fixing it either, but I have opened an issue now: ​https://github.com/kfl/mosml/issues/75
