[Mono-osx] Overriding DrawRect in a generic class derived from NSView results in "MethodInfo cannot be in a generic type"

I have a class for a custom control I am porting from WPF to MonoTouch and
MonoMac. The class is a generic and I have derived it from NSView like
class NumericControl<TData, TOffset> : NSView
// constructors and initializers etc.
// draw the control
public override DrawRect(RectangleF rect)
// draw something
This all works fine in MonoTouch.
When I instantiate the class in the WindowDidLoad of my
MainWindowController class in MonoMac like this
NumericControl<double, double> numeric1 = new NumericControl<double,
I get a System.ArgumentException "MethodInfo cannot be in a generic type".
If I derive another non-generic class from the generic and put the
DrawRect override in there everything works fine.
This seems like a bug in MonoMac or at least a gap in the implementation.
