Adding NotifyTrack from AnimDataModifier doesn't refresh Animation Editor

When creating a Notify Track using an Animation Modifier in the Animation tab of an Animation Sequence, the new Track added and applied fails to appear in the Notifies panel until the panel has been collapsed and expanded.

Reported and tested in version 4.25.3 (CL-13942748) and version 4.24.3 (CL-11590370)

Error not appearing in 4.24.3; UI has changed between that and version 4.25.3. 

1. Create Animation Modifier that adds a new Notify Track.
2. Add Animation Modifier to Animation Editor and apply.
3. Collapse and expand Notifies tab to make the new Track visible.

Results: Notify Track is not listed. If you collapse and expand Notify Tracks, the new Track appears.

Expected: When tracks are modified externally (using the Animation Data Modifier), the Animation Editor should refresh. Or - the Animation Editor should refresh automatically after any Animation Data Modifier was run and finished.
