SubtleCrypto providing invalid CryptoKey

I'm trying to import a public key using importKey, but it just returns an empty CryptoKey, meanwhile in NodeJS it'll import just fine. Code:

const publicKey = await crypto.subtle.importKey(
  "spki",
  Buffer.from(
    "3059301306072a8648ce3d020106082a8648ce3d03010703420004ea1371a3dca5e8a934bf5e434ead0aeee951cc1d09774df2f1aa6948dde7c67cb4bc62502d1d05e03e7ae318820875ff988093e14cc541660366b5af868267c4",
    "hex"
  ),
  { name: "ECDSA", namedCurve: "P-256", hash: { name: "SHA-256" } },
  true,
  ["verify"]
);

const publicKey = await crypto.subtle.importKey(
  "spki",
  Buffer.from(
    "3059301306072a8648ce3d020106082a8648ce3d03010703420004ea1371a3dca5e8a934bf5e434ead0aeee951cc1d09774df2f1aa6948dde7c67cb4bc62502d1d05e03e7ae318820875ff988093e14cc541660366b5af868267c4",
    "hex"
  ),
  { name: "ECDSA", namedCurve: "P-256", hash: { name: "SHA-256" } },
  true,
  ["verify"]
);

On the worker runtime it returns

CryptoKey {
  usages: undefined,
  algorithm: undefined,
  extractable: undefined,
  type: undefined
}

CryptoKey {
  usages: undefined,
  algorithm: undefined,
  extractable: undefined,
  type: undefined
}

In NodeJS it returns

CryptoKey {
  type: 'public',
  extractable: true,
  algorithm: { name: 'ECDSA', namedCurve: 'P-256' },
  usages: [ 'verify' ]
}

CryptoKey {
  type: 'public',
  extractable: true,
  algorithm: { name: 'ECDSA', namedCurve: 'P-256' },
  usages: [ 'verify' ]
}

Using X509Certificate

Is there any way to parse and verify certificates in workers? It seems like it's unsupported in node_compat, but my only other solution is to host a NodeJS server, only for parsing certificate signed JWT tokens.
