5.8 Run Construction Script in Seqeuncer hiding control rigs

Controls don't display in viewport if the container blueprint has "Run Construction Script in Sequencer" enabled. We've also noticed spawned control tracks temporarily disappearing from sequencer.

Steps to Reproduce  

1. Add Manny SKM to an Actor BP
2. In BP class settings turn on "Run Construction Script in Sequencer"
3. Add BP_Manny to sequencer
4. Enter Animation Mode
5. Observe the CR tracks exist but nothing is in the viewport
6. Disable "Run Construction Script in Sequencer"
7. Observe the controls now render in the viewport
