Duplicate of Bug 1450234.

It was decided when fixing Bug 1450650 that it is desirable to have the Shape Path editor's coordinate markers extend and be interactive beyond the limits of an iframe (but within the constraints of the global viewport). 

Shapes with coordinates which extend beyond the viewport are valid declarations and there are use cases where a web designer may want to use that.
