The scroll bar does not appear on flex box

My flex child is a text caption that contains a reading selection (much longer than a caption, but a text box was not an option). I select AUTO for overflow and in the preview no scroll bar appears. Also the text spills out of the flex box and is not hidden.


Can you please share the project which has the issue and its external data folder named in the PROJECT_FILE_files (if any) to so we can check?
