This should be fixed in the latest master (e.g. nix shell github:nix-community/nh if you have the experimental CLI enabled).

The nixpkgs fixes haven't made their way to the releases yet, unfortunately. See https://nixpk.gs/pr-tracker.html?pr=469136 for unstable and https://nixpk.gs/pr-tracker.html?pr=469449 for 25.11.
