How to reproduce:
1. Open the attached “IN-82890” project
2. Open the “SampleScene” and enter Play mode
3. Observe the Console window and take note of the order of bindings (Root, Hips, Spine, Spine1, LeftUp, RightUpLeg)
4. Select the “test001” asset in the Project tab
5. In the Animation window (Window → Animation → Animation), delete a keyframe from “Spine1 : Rotation”
6. Enter Play mode
7. Observe the Console window
Expected Result: The order of the list returned by AnimationUtility.GetCurveBindings should be in a DFS traversal order, no matter what changes are made
Actual Result: The order of the list returned by AnimationUtility.GetCurveBindings is changed where the bindings that have the latest changes are rearranged to the end of the list
