Allow canceling the like/dislike status in gr.Chatbot

[HenryBao91]

• I have searched to see if a similar issue already exists.
  I installed the newest version:

pip install https://gradio-pypi-previews.s3.amazonaws.com/936988dbbfd3cb1431ecd59fd7061e0217fe66f1/gradio-5.9.1-py3-none-any.whl

My Code is here：

import gradio as gr

disliked_messages = {}

def greet(history, user_input):
    return history + [{"role": "user", "content": user_input}, {"role": "assistant", "content": "Hello, " + user_input}], gr.update(value="")  

def vote(data: gr.LikeData, history):
    print(data.index, data.liked)
    
    if isinstance(data.index, int):
        message = history[data.index]["content"]  
    else:
        message = ""
    
    if disliked_messages.get(message, False):  # dislike -> cancel dislike
        disliked_messages[message] = False
        print("You canceled the dislike for this response: " + message)
    else:  
        disliked_messages[message] = True
        print("You disliked this response: " + message)
    
    updated_history = [
        {"role": item["role"], "content": item["content"]} if disliked_messages.get(item["content"], False) else item
        for item in history
    ]

    return gr.update(value=updated_history)

with gr.Blocks() as demo:
    chatbot = gr.Chatbot(feedback_options=["Dislike"], type="messages") 
    textbox = gr.Textbox()
    textbox.submit(greet, [chatbot, textbox], [chatbot, textbox])  
    chatbot.like(vote, [chatbot], chatbot) 

if __name__ == "__main__":
    demo.launch()

No matter how I modify the vote function, when I click on "thumb-down" again, "Dislike" cannot be canceled.

When I click “thumb-down” ,it turn to

and if I click “thumb-down” again, it turn to

but now:
