Conditional Visibility based on Rich Text Fields Bug Returns

The conditional visibility bug described in this closed thread from 2019 appears to have returned.

I have a collection of posts that have a RTF where I wish to display a whole section containing that (another other) elements only when there is content in the RTF.

As a work around, I have added a switch to control the section’s visibility, but that is cumbersome for my client.

Am I missing something here?

EDIT: here’s a short video of what I’m seeing.
