### Issue description

When hovering a class name symbol, the VSCode tooltip does not show the brief description and shows the main description twice. However, all other symbols (functions, variables) work just fine.

extends Node
## A brief description of the class's role and functionality.
##
## The description of the script, what it can do,
## and any further detail.
##
## @tutorial: https://example.com/tutorial_1
## @tutorial(Tutorial 2): https://example.com/tutorial_2
```

The tooltip shows the following:
