The processor stops working after receiving the connection-change event with the state Reconnecting

Description

I am implementing an AI avatar feature using VideoProcessor. However, after encountering a network instability (receiving a connection-change event with the state Reconnecting), I noticed that the VideoProcessor no longer continues to processFrame even after I receive the Connected state again from the connection-change event.

I tried recreating the processor using createProcessor, but got the following error:

{type: 'INVALID_PARAMETERS', reason: 'You have already created this Processor', errorCode: 6121}

I also attempted to restart the existing processor, but it seems that the MessagePort inside the processor is no longer functional, as I can no longer receive any messages from it.

Web Video SDK version: 2.2.5

Video SDK Code Snippets

Listening for messages in VideoProcessor:

class AvatarProcessor extends VideoProcessor {
  constructor(port: MessagePort, options?: any) {
    super(port, options);

    port.addEventListener('message', async (e) => {
      console.log('AvatarProcessor received message:', e.data);
    });
  }

}

Where the event is sent:

  sendMessage(type, data) {
    this.processor?.port.postMessage({
      'type': type,
      'data': data
    });
  }
