Summary

Right-side label of st.slider and st.select_slider overflows when inside st.expander.

In the past I submitted a similar issue for the left-side label (see #5898); now it is the right-side label that is misbehaving.

Reproducible Code Example

import streamlit as st

st.title("Right-side label of slider and select_slider overflows when inside expander")

with st.expander('Example st.expander'):

    single_value = st.slider(
        label='Example st.slider',
        min_value=9_500_000,
        max_value=10_000_000,
        value=10_000_000
    )

    first_value,last_value = st.slider(
        label='Example st.slider (range mode)',
        min_value=9_500_000,
        max_value=10_000_000,
        value=(9_500_000,10_000_000)
    )

    single_value = st.select_slider(
        label='Example st.select_slider',
        options=['Maradona','Ronaldo','Pele','This is a very, very long label'],
        value='This is a very, very long label'
        )

    first_value,last_value = st.select_slider(
        label='Example st.select_slider (range mode)',
        options=['Maradona','Ronaldo','Pele','This is a very, very long label'],
        value=['Maradona','This is a very, very long label']
        )

Steps To Reproduce

1. Run the reproducible code example
2. Open the expander and see that all the right side labels are overflowing

Expected Behavior

Labels should not overflow beyond the widgets width.

@marduk2 Thanks for reporting this issue. I was able to reproduce it here. It seems to happen after the second expansion:
