Spawnable Actor Component parameters are not saved without being keyed

Spawnable Actor Component parameters are not saved without being keyed

1. Create a Blueprint and add a point light component to it
2. Create a Sequence and add the blueprint as a spawnable actor
3. Select the BP Actor Track
4. In the Details panel, select the Point Light component
5. Change the light color
6. Close the sequence
7. Re-open the sequence

Result: Light is back to default color
Expected: Like the overall BP component parameters, they should be saved

[BUG] Sequencer reset parameter changes on components
