Object put on a Media Frame will appear displaced in Hubs if the Media Frame is in a Group that had been moved in Spoke

To reproduce:

1. Create a new project in Spoke
2. Create a suitable object to place a Media Frame on (tested for 2D)
3. Put a Media Frame on that object
4. Create a Group
5. Move the object and the Media Frame into that Group
6. Select the Group and move it to a different location in the scene
7. Everything seems fine at first, publish the scene
8. Create a Hubs room with that scene
9. In Hubs, place a (2D) object on the Media Frame
10. The object seems to snap correctly at first, but finally will appear displaced, at the original location of the Media Frame before the Group was moved

Expectation: The object should appear for good where the Media Frame actually is
