Existence of Static Function Prevents Access of Unrelated Static Variable

### Tested versions

Reproducible in 4.2stable, 4.3 stable

### System information

Windows 11 - Godot 4.2stable, Godot 4.3 stable

### Issue description

I truly do not know why this is the case, but in my project the very existence of the below code causes a crash when attempting to access an unrelated static variable. This function is not called before the crash occurs.

```gdscript
class_name CardHelpers
...
static func arrow_to_target_k(origin:CardStub, target:PilotButton)->void:
#TODO: Add color and/or texture as arguments
var arrow:TargetArrow = load("res://engine/common/ui_scenes/target_arrow.tscn").instantiate()
origin.add_child(arrow)
arrow.unpack(origin.global_position, target.global_position)
```

The existence of "arrow_to_target_k" causes a crash elsewhere in the project when attempting to access a static variable.

This code:

```gdscript
class_name CardHelpers
....

static func card_by_id(id:String, origin:String)->LogicalCard:
if origin == "pilot":
return PilotCardLib.lib[id]
```

causes the error below:

`Invalid access to property or key 'lib' on a base object of type 'GDScript'.`

### Steps to reproduce

Hit "new game" after running this branch: https://github.com/BluntBSE/ultra_mayor_2/tree/non_crashing_example
to see intended behavior

### Minimal reproduction project (MRP)

Steps to reproduce not exactly known. Crashing/non crashing branches posted above.

_Bugsquad edit:_ Fix codeblock formatting.

Start by comparing the non_crashing_example and crashing_example branches, then reproduce the failure by hitting “new game.” Investigate how GDScript handles the presence of the unused static function and the later access to PilotCardLib.lib; done means the crashing branch no longer reports invalid access to 'lib' while preserving the intended behavior.
