[Timeline] After copy pasting the track group, seeking the original one causes lagging
To reproduce:
1. Open user's attached project ("TestTimelineCP.zip")
2. Open "main" scene
3. In hierarchy window select "Cube A"
4. In timeline window copy its track group
5. Select "Cube B"
6. Paste copied track
7. Attach Cube B animator to the copied track
8. Notice that moving the white marker on Cube B timeline is smooth
9. Repeat step 7 on Cube A
Expected result: Moving the marker on Cube A should be also smooth
Actual result: Moving the marked on original track (Cube A) is very laggy
