[Issue] When using st_folium, a blank space will be left below the map

[leons1982]

Issue Desc: When I use st_folium on the latest version of streamlit, after the map is rendered, a large blank area is left at the bottom of the map
Issue Image:

Versions I used:

• streamlit:1.36.0
• streamlit-folium:0.21.0
• folium:0.17.0

Code to reproduce the issue:

import folium
import streamlit as st
from streamlit_folium import st_folium

m = folium.Map(location=[39.949610, -75.150282], zoom_start=5)

with st.container(border=True):
    st_folium(m, height=500)

Additional information:
When I use the folium_static function, the map can be rendered normally without any white blank area, but I need to get the information returned by the map, so I need to use st_folium

Please check this issue caused by streamlit version upgrade, it will be of great help to me, thank you!

It's not immediately obvious what the issue might be, but if this only happens when you upgrade the Streamlit version, you might try filing a bug with them as well? I can't think of a change we've made recently that would affect the underlying container (the code of which comes from Streamlit as part of the custom components functionality)

Ok,I will report the issue the streamlit team too, thanks.
