// ConnectDevToolsAgent takes an associated interface, which normally needs to
// be passed through a different pipe to be usable.  The usual way of testing
// this is by using BindNewEndpointAndPassDedicatedReceiver to force creation
// of a new pipe.  Unfortunately, this doesn't appear to be compatible with how
// our threads are setup.  So instead, we emulate how this would normally be
// used: by call to a worklet, and just have a mock implementation that only
// supports ConnectDevToolsAgent.
