TypeScript Definition for CameraPopoverOptions does not declare class

The docs for CameraPopoverOptions use it as a class.

From docs: 

var cameraPopoverOptions = new CameraPopoverOptions(0, 0, 100, 100, Camera.PopoverArrowDirection.ARROW_ANY);

But the index.d.ts only define an interface, not declare a class, so using it as a class in a TypeScript file gives the error:
[ts] 'CameraPopoverOptions' only refers to a type, but is being used as a value here.

The fix would be to declare a class and constructor.

declare class CameraPopoverOptions implements CameraPopoverOptions {
    constructor(x?: number, y?: number, width?: number, height?: number, arrowDir?: number);
}
