"""Restore Streamlit v0.88.0 session state behavior.

The legacy session state behavior allowed widget states to be persistent,
even after their disappearance. This can be handy when making a configurable
settings page.

Usage
-----

You must call the legacy_session_state() at the beginning of your script.
