Follow-up after: https://bugs.webkit.org/show_bug.cgi?id=299508 With site isolation, GetAccessibilityPropertiesForElement and GetAccessibilityPropertiesForAccessibilityNode (bug 299508) can’t walk the accessibility tree across a frame hosted by another Web Process. A cross-origin iframe appears in the parent frame’s tree as a childless RemoteFrame node, and the iframe’s root has no parent. Possible fixes: return a frame reference from the RemoteFrame node so clients can continue in that frame, or stitch the trees together in the UI Process.
