Timeline's property panel looses names and bindings when selecting clips.

This is repro with two specific clips Timeline's Default Track sample when the Inspector window is open.
Closing the Inspector window avoids this issue.

repro:
- Open attached project & scene
- Select and open Timeline
- make sure the Inspector window is also open
- expand Building group
- select the 2 clips on the second Control track...
bug: property panel looses names and bindings
expected: clip selection does not affect names and bindings
