JS scripts in Tests and Pre-req Tabs are a plain text

Hi! I am using the deckstop Postman App on my Mac. Why is my script in the Tests tab (Pre-req tab) is not colorized (highlighted) and displayed as a plain text? In the web app it’s ok. How to make the code colorized like in any IDE or at least in the Web App?

Closing this as it’s the same topic.
