Bug - ExpandableSection - If the text change on-the-fly the "Show more" button is not rendered correctly.

In the ExpandableSection component if the text change on-the-fly the "Show more" button is not rendered correctly.

I have created a sandbox example here:
https://codesandbox.io/s/stupefied-microservice-vj4y7c

The component should render the "Show more" button if the text change dynamically without refreshing the page.

This was tested in the chrome version 108.0.5359.125 (Official Build) (64-bit)

Hi, it's possible to do a backport of this fix to the version 4?

Thank you in advance.
