Godot version

v4.2.beta3.official [e8d57af]

System information

Godot v4.2.beta3 - Pop!_OS 20.04 LTS - X11 - Vulkan (Forward+) - integrated Intel(R) UHD Graphics 630 (CFL GT2) () - Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz (16 Threads)

Issue description

An enum always appears in the help window, even if it is not preceded by documentation and its name starts with an underscore .

This is not consistent with the behavior of other items.

# The below function isn't documented and its name starts with an underscore
# so it will treated as private and will not be shown in the help window.
func _internal() -> void:
	pass
