RDragZoom does not extend RDragBox and onChange appears not to work

[deirdrehall]

In the OL 9 standard, DragZoom extends DragBox and should give access to the same functions (onBoxStart / onBoxEnd / etc)

In addition, the onChange defined on RDragZoom does not ever seem to activate:

        <RInteraction.RDragZoom
          condition={alwaysCondition}
          onChange={(e) => {
            console.log("RDragZoom onChange fired");
          }}
        />

The RDragZoom is properly defining a box and zooming to that box, but nothing is ever logged to the console.

I have other map functionality which needs to be disabled when RDragZoom is active, and I have not been able to figure out a way to detect when it is active.
