Page layout is not "centered" by default in multipage apps #6237
Description
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
Page layout is not "centered" by default in multipage apps, as would be expected by the default value in st.set_page_config.
Instead, it inherits the layout from the previously visited page.
I would call it a bug, but could also hear that this is expected because no explicit call to st.set_page_config was made...
Example:
Reproducible Code Example
#streamlit_app.py
import streamlit as st
st.write(st.__version__)
st.title("Hello world")#pages/one.py
import streamlit as st
st.set_page_config(layout="wide")
st.title("Wide layout")
#pages/two.py
import streamlit as st
st.set_page_config(layout="centered")
st.title("Centered layout")
### Steps To Reproduce
_No response_
### Expected Behavior
The `streamlit_app` page should have its layout = `"centered"`, as is meant to be the default for `st.set_page_config()`.
### Current Behavior
The `streamlit_app` page inherits its layout from the previously visited page
### Is this a regression?
- [ ] Yes, this used to work in a previous version.
### Debug info

- Python version:
- Operating System: Mac OSX
- Browser: Chrome
- Virtual environment: None
