WebKit's Digital Credentials implementation supports only the org-iso-mdoc presentation protocol: DigitalCredentialPresentationProtocol has a single value (OrgIsoMdoc), and the WebKitTestRunner virtual-wallet bridge (WebPageProxy::setVirtualWalletBehaviorForTesting) ignores the requested protocol and always responds as org-iso-mdoc. As a result, the imported WPT test digital-credentials/webdriver/get-openid4vp.https.html (which requests and asserts the openid4vp-v1-unsigned protocol) cannot pass and is skipped. There are no current plans to support openid4vp presentation; this tracks the gap so the test can be un-skipped if that changes.
