Question

In the gui_in_3d demo the mouse over highlight works on buttons and sliders, but if you add a scroll bar it does not show mouseover highlight for scroll bar?

extends Node3D

## Used for checking if the mouse is inside the Area3D.
var is_mouse_inside := false

## The last processed input touch/mouse event. Used to calculate relative movement.
var last_event_pos2D := Vector2()

## The time of the last event in seconds since engine start.
var last_event_time := -1.0

@onready var node_viewport: SubViewport = $SubViewport
@onready var node_quad: MeshInstance3D = $Quad
@onready var node_area: Area3D = $Quad/Area3D

func _ready() -> void:
	node_area.mouse_entered.connect(_mouse_entered_area)
	node_area.mouse_exited.connect(_mouse_exited_area)
	node_area.input_event.connect(_mouse_input_event)

It works when the ui is extracted to a 2d scene and run like that. scroll bar shows mouse over highlight. But in 3D not work?
It works fine for buttons and sliders.
It shows the highlight sometimes if you click around on the bar to move the grabber around a bit and then correctly un-highlights when move off bar… but should show on mouse over like it does for other controls?

Here is a simple test or can try in gui_in_3d.

I guess just a bug? Unless anyone has any input I will post an issue.

Thanks.
