Notice how the hue is on the blue color, but the saturation is insists on remaining red.

If I change the saturation a little bit, the correct value will apply. But if I adjust the value or the alpha, the blue hue will be punched out and become red again.

### Steps to reproduce

Go to a ColorPicker in the editor (say, the modulate property of Node2D), open the color picker, and copy the above configuration in the HSV tab.

### Minimal reproduction project

N/A
wheel_shader.instantiate();
	wheel_shader->set_code(R"(
// ColorPicker wheel shader.
