### Expected

As it does in the Godot versions before: 4.1.beta1

### Steps to reproduce

- open the attached project: [issue, mouse over slider, handle highlight, offset.zip](https://github.com/godotengine/godot/files/11714943/issue.mouse.over.slider.handle.highlight.offset.zip)
Node2D is selected, in the Scene panel, and the Transform group/section is unfolded in the Inspector panel.
- move the mouse over the Transform > Rotation, slider

### Observed

The sliders mouse-over handle highlight (a circle with a ring around it) appears offset (down and to the right) from the sliders handle.

The mouse-over handle highlight moves to the slider handle when:
- the mouse is held still over the slider until the tooltip appears
- or if the mouse is moved away from the slider and back over the slider

Now the second and subsequent slider mouse-overs keep showing the handle highlight correctly.

The issue can be reproduced by deselecting and selecting Node2D in the Scene panel.

### Expected
