How to reproduce:
1. Open the attached project "seq-save-scene-reset-timeline.zip"
2. Open the TestScene (Assets>TestScene)
3. Open the Timeline (Window>Sequencing>Timeline) and place it that you always can see it (like in "Layout.png")
4. Select and expand GameObject "Driver" in the Hierarchy
5. In the Timeline window move the Playhead between Clip 1 and Clip 2 to see it enabling and disabling
6. Select GameObject "Cube" in the Hierarchy
7. Move the selected "Cube" GameObject in the Scene view
8. Select GameObject "Driver" in the Hierarchy
9. Save the Scene

Expected result: After the save states are the same as before saving
Actual result: Both Clips are now disabled in the Hierarchy but Playhead still is on Clip 1
