Describe the bug:
On the canvas embeddable workpad, added a sample flight data element, clicked clone of the image. It cloned an empty image without any data points.
The data points are visible in full screen mode.

Steps to reproduce:

1. Open a new canvas workpad and embed an object - I chose sample data flights.
2. Click on Clone - it clones the object - but the object is blank . ( no console errors )
3. tried on different browsers- Chrome and Firefox - same behavior. Logs are clean.
4. Now open the workpad in Full screen mode- the cloned object is seen with the data points.
