SUMMARY
Two sequences. Seq1 is in Seq2's timeline. When Seq1 length has been changed, changes not correctly updated in Seq2 timeline.

STEPS TO REPRODUCE
1. Add two color clip to Seq1's timeline. (ColorClip1 at 00:00, colorClip2 at 00:30)
2. Add Seq1 to Seq2's timeline
3. Switch to Seq1. Drag and move ColorClip2 to left
4. Switch between Seq1 and Seq2 tab for some times. Finally switch to Seq2

OBSERVED RESULT
In Seq2's timeline, Seq1's audio track length is updated after twice switching. Video track length fail to update.

EXPECTED RESULT
In Seq2's timeline, Seq1's audio and video tracks are updated immediatly.
