GDScript 2.0: Documentation comments do not appear in inspector tooltips

[h0lley]

Godot version

v4.0.alpha4.official [f470979]

System information

Ubuntu, Nvidia, Vulkan

Issue description

Looking at the merged PR #41095, inspector tooltips for @export variables should already be implemented. However, I can't get them to show up. They do appear in the documentation (F1) just fine, but the tooltip text remains "No description".

A restart of the editor does not help.

Steps to reproduce

Code used in above example:

extends Node
class_name MyClass

## My documentation for my_inspector_setting
@export var my_inspector_setting: int

Or get the minimal reproduction project,

1. Press F1 and check the docs of MyClass, notice the description of my_inspector_setting
2. Open main.tscn and hover the property in the inspector, notice "No description"

Minimal reproduction project

What's up with this feature ?
This has been removed from the 4.0 milestone, is it expected to be in 3.5 or is it just stranded ?

[akien-mga]

It's not critical to solve before releasing 4.0, so in such case we don't put a milestone, which just means it will be fixed when it's fixed. Would still be nice to have fixed in 4.0 of course if anyone wants to work on it.

Original proposal has been around since 2016 ( #4370 )
Couldn't we do something to speed up the process for 4.0 ? Maybe asking directly in discord or something, It seems like a long-requested update

[akien-mga]

That proposal has been implemented already, and works fine. What's missing is literally just hooking it up in tooltips, which can be done by any motivated contributor.

in opening post I mentioned that this should already be implemented judging by the screenshot in #41095 so I thought let's bisect it, but I just compiled 42bfa16 and was still unable to get tooltips, so perhaps the screenshot was just a concept.
@ThakeeNathees perhaps you could clarify. have tooltips been implemented at some point?
