Too many arguments provided for the endpoint - JavaScript-Warning in browser console

Describe the bug

When launching a gradio application with gradio.Chatbot or gradio.ChatInterface, there is a JavaScript-Warning in the browser console every time a message is submitted:

Too many arguments provided for the endpoint.

You can also see these warnings in the chatbot-boxes in the official gradio documentation or in the gradio playground.

My analysis so far:

Apparently, endpoint_info is undefined here. Therefore, the length of parameters can never correspond with those parameters that one tries to send. I also don't really understand about which endpoints all of this is, after all. Also, I don't know what this "/info"-endpoint is that is referenced here. Regardless of the length of this parameter, the function in which it is located will always be terminated early, or the input data will be returned unchanged. However, the 'fix' that is now causing the warnings was likely introduced by this commit / #8820.

There are no practical problems due to this warning in our chat applications. However, we don't really want to deploy anything that causes warnings. Is there a way to prevent this warning?

Reproduction

import random
import gradio as gr

def random_response(message, history):
    return random.choice(["Yes", "No"])

gr.ChatInterface(random_response, type="messages").launch()
