Some objects may be out of sync until you rejoin

[parseccentric]

Bug Description

When joining a session that someone else is in, object properties are not in-sync.

Steps to reproduce

1. Have someone else join a session and interact with models. (Don't join the session yet.)
2. Join the same session yourself after they've done that.
3. Compare the transforms (position, rotation, scale) of the models.
4. Compare the visibility state of the models.
5. Compare the lock state of the models.
6. Press one of the Rejoin buttons (in the People tab).
7. Repeat the comparison steps.

Expected Result

Before and after pressing rejoin, the objects are synced correctly.

Actual Result

Only after pressing rejoin are the objects synced correctly.
