Describe the bug

rerun_example_disconnect_space does not work if TimeSeriesScalar is logged in python.

To Reproduce
Steps to reproduce the behavior:

1. Run:

        # Slightly modified example code for disconnect space
        rr.init("rerun_example_disconnect_space", spawn=True)
   
        # These two points can be projected into the same space..
        rr.log("world/room1/point", rr.TimeSeriesScalar(0))
        rr.log("world/room2/point", rr.TimeSeriesScalar(1))
   
        # ..but this one lives in a completely separate space!
        rr.log("world/wormhole", rr.DisconnectedSpace())
        rr.log("world/wormhole/point", rr.TimeSeriesScalar(3))
   

2. Look in the viewer for disconnected spaces.

Expected behavior

Two different spaces should be shown, but as stated, all signals are shown in one single space.
