### Godot version

### System information

Godot v4.1.rc2.mono - EndeavourOS #1 SMP PREEMPT_DYNAMIC Thu, 11 May 2023 16:40:42 +0000 - Vulkan (Forward+) - integrated Intel(R) HD Graphics 4400 (HSW GT2) () - Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz (4 Threads)

### Issue description

When using [GDScript documentation comments](https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_documentation_comments.html) to create description tooltips for [@export variables](https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_exports.html), they do not show up in the editor if:

- The export variable requires arguments (eg. [@export_enum](https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_exports.html#exporting-enums)), and the arguments are declared across more than 2 lines. [(recommended by GDScript style guide)](https://docs.godotengine.org/en/stable/tutorials/scripting/gdscript/gdscript_styleguide.html#format-multiline-statements-for-readability)
- A description is applied to an [@export_category](https://docs.godotengine.org/en/stable/classes/class_%40gdscript.html#class-gdscript-annotation-export-category). 
  - This error also applies to all variables within the category

To illustrate, here are some screenshots from the included minimal reproduction project.

### Steps to reproduce

Copy-paste this code into a new node's script. A minimal reproduction project with all this prepared is included below for convenience.

```
extends Node


## This shows up in the editor.
@export_enum("example1", "example2",) var good_enum


## [i]This shows up in the editor, but goes against recommended practices.[/i]
@export_enum(
	"example1", "example2",) var poor_practice_multiline


## THIS DOES NOT SHOW UP IN THE EDITOR.
@export_enum(
	"example1",
	"example2",
) var bad_enum

## THIS DOES NOT SHOW UP IN THE EDITOR.
@export_category("Categories truncate comments")

## THIS DOES NOT SHOW UP IN THE EDITOR.
@export var bad: int
```
