The WebDriver BiDi digitalCredentials agent stores per-context virtual wallet behaviors and parked "wait" completion handlers, but those maps are only cleared when the automation session ends. On a WebProcess crash or a page/frame closing without a JS-side abort, the entries persist until session end. A destruction hook (page-level as well, since willDestroyFrame only fires for subframes) should drain the maps. Memory-safe (leak, not crash). Follow-up to the Digital Credentials WebDriver support (bug 306292) and the WebKitTestRunner support (bug 318290).
