CastPlayer crashes when Receiver has error in LOAD message interceptor

Version

Media3 1.1.1

More version details

When our Cast Receiver has an internal exception/error inside a LOAD message interceptor, the CastPlayer on the Sender app is crashing like so:

// Cast Receiver error, unsure if this is helpful.  This is our bug that needs to be fixed
playerManager.setMessageInterceptor(
  cast.framework.messages.MessageType.LOAD,
  request => {
      // do something bad here that causes an exception in the JavaScript
  }
);

// Cast Sender crashes here
java.lang.IllegalStateException
