• I have provided sufficient information below to help reproduce this issue.

Summary

If you have two separate dialogs in your app, opening the first dialog, closing it, and then opening up the second dialog can lead to stale elements from the first dialog showing up in the second dialog. This only happens if the second dialog takes a while to load.

Reproducible Code Example

import streamlit as st
import time

@st.dialog("Dialog 1")
def show_dialog_1():
    st.write("Dialog 1 content")
    st.text_input("Text input")

@st.dialog("Dialog 2")
def show_dialog_2():
    time.sleep(3)
    st.write("Dialog 2 content")


if st.button("Open dialog 1"):
    show_dialog_1()

if st.button("Open dialog 2"):
    show_dialog_2()

Steps To Reproduce

1. Open the first dialog
2. Close it
3. Open the second dialog

Expected Behavior

No content from show_dialog_1 shows up in show_dialog_2 since these are independent dialogs.

Current Behavior

See video.

Is this a regression?

• Yes, this used to work in a previous version.

Additional Information

I think the cleanest solution might be to clear all elements from the dialog when it gets closed or opened.
