This and the same below sadly results in error log output e.g. when testing applets with plasmoidviewer:

  file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:61:5: Unable to assign [undefined] to int
  file:///usr/share/plasma/plasmoids/org.kde.desktopcontainment/contents/ui/main.qml:52:5: Unable to assign [undefined] to int

Seems to be able to assign `null` or `undefined` to a property the respective property needs to have a `RESET` method defined.

Unsure myself what undefined even should mean here, and whether a RESET method is better than just assigning some dummy value here.
