   @dajac I'm having a bit of a hard time figuring out how to test this.
   
   Per your previous comments, the `NetworkClient` already issues a request for metadata update when the connection disconnects. However, because the `SenderTest` doesn't leverage `NetworkClient`, and instead uses `MockClient`, it's not possible to rely on that behavior.
   
   To fix this, I tried to update `MockClient` to have similar semantics to the `NetworkClient` with respect to when it handles disconnects and metadata updates, but that doesn't really "feel" right because it doesn't prove anything. I'm now thinking that I need to maybe handle this test in an integration test. I'll look into that now.
   
   Thanks
