>+        We used to have a bug where where we would fail to wait for the policy decision for
>+        the navigation response from the client and the load would keep going, racing with
>+        the client's policy decision. If the client did not respond in time, the behavior
>+        would be the same as "Use" policy action.
>+
>+        Box.app fails to make any policy decision in its decidePolicyForMIMEType delegate
>+        but the load happened to proceed anyway due to our bug. Now that we've fixed the
>+        WebKit bug, however, the load would hang because the completion handler for the
>+        decidePolicyForNavigationResponse would never get called.
>+
>+        To work around the issue, I made the policy listener weak on the WebFrameLoaderClient
>+        instead of retaining it. If the policy listener object gets destroyed because getting
>+        resolved, we now use "Use" policy action in its dealloc function to maintain previous
>+        behavior.
