Bug: Godot documentation cross-references to autoload enums fail from other script files

[edzillion]

Problem Description

Cross-references to enums defined in autoload scripts don't work when referenced from other script files within the same addon using Godot's built-in documentation system.

Specific Issue

In helper_functions.gd, attempting to create documentation links to StatMath.SupportedDistributions enum (defined in the StatMath autoload) results in:

• Links that appear clickable but lead to blank pages
• Links that don't navigate anywhere when clicked

Steps Attempted

We tried multiple cross-reference syntaxes as documented in Godot's documentation system:

1. [enum StatMath.SupportedDistributions] - Creates link that goes to blank page
2. [enum SupportedDistributions] - Creates link that does nothing when clicked
3. [member StatMath.SupportedDistributions] - Creates link that goes to blank page
4. [constant StatMath.SupportedDistributions] - Creates link that goes to blank page

Current Workaround

Reverted to using [code]StatMath.SupportedDistributions[/code] which provides proper formatting without broken links.

Expected Behavior

Cross-references should properly link to the enum definition in the StatMath autoload and navigate correctly when clicked.

Environment

• Godot Version: 4.4
• Project Type: GDScript addon
• Autoload Setup: StatMath registered as autoload pointing to res://addons/godot-stat-math/stat_math.gd

Additional Context

• The enum is properly documented with ## comments in the StatMath autoload
• The autoload is correctly registered in project.godot
• Cross-references work fine for built-in Godot types (e.g., [enum MouseButton])
• Issue appears specific to enums in custom autoload scripts

Code References

Enum definition (stat_math.gd):

## Supported statistical distributions for various calculations
enum SupportedDistributions {
    NORMAL,     ## Normal (Gaussian) distribution  
    STUDENT_T,  ## Student's t-distribution
    CHI_SQUARED ## Chi-squared distribution
}

Failed cross-reference (helper_functions.gd):

## Converts a string distribution name to [code]StatMath.SupportedDistributions[/code] enum.
static func string_to_distribution_enum(distribution: String) -> StatMath.SupportedDistributions:
