Customize the set_page_config about page width

[Grant_Culp]

Summary

I am utilizing the about page element within the function set_page_config. This is within the menu_items dictionary.
Is there a way to increase the size of the popup that shows up?

Steps to reproduce

Code snippet:

import streamlit as st

st.set_page_config(
    page_title="Ex-stream-ly Cool App",
    page_icon="🧊",
    layout="wide",
    initial_sidebar_state="expanded",
    menu_items={
        'Get Help': 'https://www.extremelycoolapp.com/help',
        'Report a bug': "https://www.extremelycoolapp.com/bug",
        'About': "# This is a header. This is an *extremely* cool app!"
    }
)

If applicable, please provide the steps we should take to reproduce the error or specified behavior.

Expected behavior:

Have the ability to increase the size of that popup window.

Actual behavior:

Stuck to a standard small size
