I couldn't track how far back that change happened so I can't fully say what these Properties actually were, but to my knowledge both properties were replaced by `ownerNode` and `ownerWindow` Properties respectively. New Properties are read-only and are set while calling respective `Popup.show()` - `Popup.show(Node, ...)` sets both Properties, while `Popup.show(Window, ...)` sets only `ownerWindow` Property.

Since there is no `Popup.show(Scene, ...)` those cases were also eliminated. This leaves current test pool into three separate parameters for one, similar test case.

We do seem to have this funny-looking `PascalCase_camelCase_Test` convention in several places.
