Can't move/resize vtkEllipseWidget

Web vtk.js
1

Hello everyone. I’m working on a widget serialization/deserialization feature. I’m able to create a widget out of serialized state by doing this:

    const widget = vtkEllipseWidget.newInstance()
    const widgetRep = widgetManager.addWidget(widget, ViewTypes.SLICE)
    const widgetJson = localStorage.getItem("WIDGET")
    const state = JSON.parse(widgetJson)

    widget.getWidgetState().getEllipseHandle().setOrigin(state.ellipse)
    widget.getWidgetState().getEllipseHandle().setScale3(state.scale)
    widget.getWidgetState().getPoint1Handle().setOrigin(state.p1)
    widget.getWidgetState().getPoint2Handle().setOrigin(state.p2)


    widget.getWidgetState().getPoint1Handle().setVisible(true)
    widget.getWidgetState().getPoint2Handle().setVisible(true)

The widget renders fine but I can’t resize it or move it around by using its handles.

I’ve tried widget.setPickable(true) and widgetManager.enablePicking() but they don’t seem to have any effect.

How can I create a widget with the typical move / resize capabilities that come out of the box by doing widgetManager.grabFocus(widget) ? Anything I’m missing?
