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
Vector<Vector2> pos;
	pos.resize(4);
	Vector<Color> col;
	col.resize(4);
	HSlider *slider = color_picker->get_slider(p_which);
	Size2 size = slider->get_size();
	Color left_color;
	Color right_color;
	Color color = color_picker->get_pick_color();
	const real_t margin = 16 * color_picker->get_theme_default_base_scale();
	if (p_which == ColorPicker::SLIDER_COUNT) {
		slider->draw_texture_rect(color_picker->get_theme_icon(SNAME("sample_bg"), SNAME("ColorPicker")), Rect2(Point2(0, 0), Size2(size.x, margin)), true);
		left_color = color;
		left_color.a = 0;
		right_color = color;
		right_color.a = 1;
		col.set(0, left_color);
		col.set(1, right_color);
		col.set(2, right_color);
		col.set(3, left_color);
		pos.set(0, Vector2(0, 0));
		pos.set(1, Vector2(size.x, 0));
		pos.set(2, Vector2(size.x, margin));
		pos.set(3, Vector2(0, margin));
		slider->draw_polygon(pos, col);
	}
