• I added a very descriptive title to this issue.
• I have provided sufficient information below to help reproduce this issue.

Summary

When hovering over certain elements (e.g. st.button or st.popover or st.expander), their label text turns red/the primary color. If the label contains colored text (e.g. the blue bar below), that text keeps its color when hovered, but it should also turn red.

Reproducible Code Example

import streamlit as st

st.button("Foo :blue[bar] baz")

Steps To Reproduce

Run code above, hover over button (or just go here 😉 )

Expected Behavior

bar turns red on hover.

Current Behavior

bar stays blue on hover.

Is this a regression?

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