Summary

Within the spinner context, if a container is created and an element within the container, (columns or tabs both create the issue) the app goes to a blank white page. This only happens if the spinner is rendered in the app, so doesn't happen if the code is ran without the sleep.

Reproducible Code Example

https://issues.streamlit.app/?issue=gh-13658

import time
import streamlit as st

with st.spinner("Running..."):
    time.sleep(2)
    st.container().columns(2)

Steps To Reproduce

1. Run above code
2. App goes blank spinner goes away after loading

Expected Behavior

Shouldn't go blank

Current Behavior

Goes blank with console error:
