Chatbot component freeze when using specific LaTeX delimiters

[GaiZhenbiao]

Describe the bug

The issue I'm encountering is reminiscent of the one documented in #7651. Specifically, when setting certain LaTeX delimiters (such as \[ and \], or $) within the Chatbot component, it ceases to function, accompanied by a JavaScript error identical to the one described in the referenced issue.

I think this malfunction likely stems from a conflict between the JavaScript responsible for markdown rendering and that for LaTeX rendering, as both systems utilize similar notation (e.g., [xxx] in Markdown). Interestingly, using $ as a LaTeX delimiter is expected to be conflict-free, I don't know what could go wrong. Besides, messages incorporating \[ and \] consistently trigger this bug 100% of the time, whereas $ results in the bug approximately 50% of the time.

Reproduction

import json
import time

import gradio as gr

with open("chatbots3.json", "r") as f:
    data3 = json.load(f)

with open("chatbots4.json", "r") as f:
    data4 = json.load(f)

def update_chatbot3():
    for d in data3:
        time.sleep(0.005)
        yield d

def update_chatbot4():
    for d in data4:
        time.sleep(0.005)
        yield d

latex_delimiters_set = [
        # {"left": "$$", "right": "$$", "display": True},
        # {"left": "\\(", "right": "\\)", "display": False},
        {"left": "\\[", "right": "\\]", "display": True},
        {"left": "$", "right": "$", "display": False},
    ]

with gr.Blocks() as demo:
    chatbot = gr.Chatbot(
        latex_delimiters=latex_delimiters_set,
    )

    trigger_btn3 = gr.Button("Trigger Chatbot Bug [] (100% triggers bug)")
    trigger_btn4 = gr.Button("Trigger Chatbot Bug $$ (~50% triggers bug)")
    trigger_btn3.click(update_chatbot3, [], chatbot)
    trigger_btn4.click(update_chatbot4, [], chatbot)

demo.queue().launch()

Severity

I can work around it

BTW, gradio webUI would also break down if set latex_delimiters_set like this

latex_delimiters_set = [
        {"left": "\\begin{equation}", "right": "\\end{equation}", "display": True},
        {"left": "\\begin{align}", "right": "\\end{align}", "display": True},
        {"left": "\\begin{alignat}", "right": "\\end{alignat}", "display": True},
        {"left": "\\begin{gather}", "right": "\\end{gather}", "display": True},
        {"left": "\\begin{CD}", "right": "\\end{CD}", "display": True},
 ]

when bot returns something like

\begin{equation}
E = mc^2
\end{equation}

---

We have noticed that after adapting to gradio4. Gradio3 is fine with mathjax and mark.js
