How to enforce a character limt in CLOB responses in Content Section blocks in application flow?

Summary:

I had assumed the 4000 character limit would apply to CLOB fields that make up content sections (e.g. Work Preferences) in the application form. However, I've just tested this and have been able to add over 8000 characters.
