Checklist

• I have searched the existing issues for similar issues.
• I added a very descriptive title to this issue.
• I have provided sufficient information below to help reproduce this issue.

Summary

When visiting an app with a URL that has an anchor link (e.g. foo.com/myapp#myanchor) Streamlit should scroll to the anchor #myanchor on the page. This is not happening today.

Reproducible Code Example

import streamlit as st

st.header("My title 1")
for _ in range(30):
    st.text("blah " * 100)

st.header("My title 2")
for _ in range(30):
    st.text("blah " * 100)

Steps To Reproduce

1. Run the code above
2. A Streamlit app will load in a browser tab
3. Open a new browser tab (it has to be a new tab!)
4. Navigate to the URL http://localhost:8501/#my-title-2

Expected Behavior

The app loads and the viewport is scrolled to "My title 2".

Current Behavior

The app loads but the viewport is at the top, at "My title 1".

Is this a regression?

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

Debug info

• Streamlit version: 1.45
• Python version: 3.13
• Operating System: MacOS
• Browser: Chrome
