### Issue description

This is a plugin description that spans 2 screens and goes beyond the right screen border.
I just wanted to test if there is any limit to plugin description size. There is none. You can potentially put a text that will cover your whole screen (don't try it 🙃).

Not sure how we should solve that. We could autowrap the label, but to gracefully display extremely long texts they either need to be scrolled (in a tooltip??) or truncated.

### Steps to reproduce

1. Open Project Settings
2. Go to Plugins -> Create New Plugin
3. Write a book in the Description field
