Steps to reproduce:
1. Create new project
2. Create an object to animate (a Cube is fine) and a Timeline controller for it
3. Record a rotation animation
4. Convert animation to timeline clip
5. In the Scene view, move the object away from the original position
6. Set an "Ease In" time value
7. Split the clip
8. Separate the clips with a small gap inbetween
9. Observe how the second clip eases in from the absolute original position rather than the one the first clip ended on

Expected behaviour: The second clip should not change the position anymore, it should now just ease into the rotation clip
Actual: The object pops back into the original position and eases in to the clips saved position
