Embedding NSOpenGlViews in a ScrollView does not produce expected scrolling behavior

Question

I have three NSOpenGLViews embedded in a scrollview. Scrolling produces unexpected behavior. The NSOpenGLViews refuse to be clipped by the bottom of the scrollview and instead will sit on the bottom of the scrollview as its resized to a smaller length. In some cases the NSOpenGlViews will then start overlapping.
