Broken Hue filter

So i found out that the hue and saturation function (gimp-hue-saturation) works from -180 to 180, like it says, as in it doesn't crash. But it only rotates the hues between -100 and 100. Any number out side of that fails to receive the hue modification.

Example:

I applied the gradient to the full circle, -180 being the top, 0 being the bottom and +180 being the top as well. But as you can see it doesn't work for all angles outside of -100 or 100
