Plotly bars with round corners

Using Streamlit
,

plotly supports bars with rounded corners.
However, it does not work with st.plotly_chart

Here is a simple code to see the issue:

import streamlit            as st
import plotly.io            as pio
import plotly.graph_objects as go

from plotly          import data
from plotly.subplots import make_subplots

def create_figure():

    df  = data.medals_wide()
    fig = make_subplots(rows=1, cols=3, shared_yaxes=True)

    fig.add_trace(go.Bar(x=df.nation, y=df.gold,   name="Gold",   marker=dict(cornerradius=10, color='green' )), 1, 1)
    fig.add_trace(go.Bar(x=df.nation, y=df.silver, name="Silver", marker=dict(cornerradius=10, color='silver')), 1, 2)
    fig.add_trace(go.Bar(x=df.nation, y=df.bronze, name="Bronze", marker=dict(cornerradius=10, color='red'   )), 1, 3)

    return fig


def main():
    st.title("Round Corners in Bar Charts")


    fig = create_figure()

    st.write('THIS DOES NOT WORK')
    st.plotly_chart(fig) #-- THIS DOES NOT WORK

    #-- THIS WORKS
    st.write('THIS WORKS')
    html_string = pio.to_html(fig)
    st.components.v1.html(html_string, height=600)

if __name__ == "__main__":
    main()

Any ideas how to make this work?

Thanks
