### Godot version

4.0 beta 10

### System information

Windows 10, Vulkan

### Issue description

While the fishbone pattern is visible, the points are not. (Invisible) points can be added to a path and deleted from it, but they can't be moved in the editor viewport, only via inspector properties.
I haven't used 4.9b, but I confirmed the point handles are visible in 4.8b on my system (same file).

### Steps to reproduce

Make a Path3d. Add points via Inspector. Fail to see point handles in the viewport.

### Minimal reproduction project

					rect.size.x -= close->get_width() + get_theme_constant(SNAME("hseparator"), SNAME("Tree"));
					if (is_layout_rtl()) {
						rect.position.x += close->get_width() + get_theme_constant(SNAME("hseparator"), SNAME("Tree"));
