The Digital Credentials specification's "request a digital credential" algorithm requires that if the requesting document stops being fully active, the credential request is aborted with an AbortError DOMException (w3c-fedid.github.io/digital-credentials/, "If document stops being fully active, abort the credential request with an AbortError"). WebKit does not abort a request that is parked pending when the requesting document — such as a subframe — becomes non-fully-active (e.g. the iframe is removed or navigated). The promise is left unsettled indefinitely. This is observable with the virtual-wallet "wait" behavior used for automated testing: a pending request in a subframe that is then removed never settles. WebPageProxy::abortPendingDigitalCredentialWaitHandlers currently fires only on page close, page reset, and chooser dismissal — not when a subframe's document becomes non-fully-active. A WPT regression test (digital-credentials/wait-non-fully-active.https.html) times out because of this; it should be landed together with the fix.
