X25519-MLKEM768 is still not prioritized over non-PQC ciphers.

With a priority string `PFS:-GROUP-ALL:+GROUP-X25519-MLKEM768:+GROUP-X25519:+GROUP-SECP256R1`, it puts X25519-MLKEM768 last, instead of first.  

With `PFS:-GROUP-ALL:+GROUP-X25519-KYBER768:+GROUP-X25519:+GROUP-SECP256R1` (the Kyber draft hybrid), X25519-KYBER768 is properly prioritized.
