We are seeing some hangs in accessibility clients that are trying to capture a snapshot of the accessibility hierarchy of a Safari window. This occurs if the window is occluded or hidden, which makes the frontmost tab's web content eligible for suspension. When the WKWebView is backed by a suspended WebContent process, the IPC to acquire the AX hierarchy in the suspended WebContent process hangs forever.
