A nit: this is not valid IDL, since WebGLRenderingContext and WebGL2RenderingContext are not distinguishable.
The good news is that the return value can just be (CanvasRenderingContext2D or WebGLRenderingContext) and still return instances of WebGL2RenderingContext if it wants to, in the same way that a method that claims to return Node can return instances of any node subtype if it wants to.
