Can you retest with wine-5.5?
This might have been influenced by https://source.winehq.org/git/wine.git/commit/ 741f76fc2c9203105ca7f87c0014bb5a9da4d936 (Hans, are you able to confirm?)
That patch is about signing with ALG_ID_ECDSA_P256 and ALG_ID_ECDSA_P384. This bug is about verifying with these algorithms, which was supported before that patch, but it depends on recent GnuTLS.
