[Bug] Incorrect zoom value shown in the overlay

[syed-qure]

Describe the Bug

The zoom value that is calculated and shown in the ViewportsOverlay component does not match with the viewport.getZoom() value.

Steps to Reproduce

1. Open a study and not the zoom value in the bottom left corner.
2. Go to console, get the enabledElement and get the zoom value from viewport object

   enabledElement.viewport.getZoom()

The current behavior

I think there is something wrong in the calculation of scale inside ViewportOverlay's updateScale function

The expected behavior

The zoom value in the ViewportOverlay component should be equal to viewport.getZoom()

Should I just use viewport.getZoom() and use its value in setScale inside ViewportOverlay and call it a day?

( evt: Types.EventTypes.CameraModifiedEvent ) => {
  const enabledElement = cornerstone.getEnabledElement( evt.element );
  const { viewport } = enabledElement;

  setScale( viewport.getZoom() );
}
