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 itโ€™s ok. How to make the code colorized like in any IDE or at least in the Web App?

Closing this as itโ€™s the same topic.
