AnimationCurve not triggering Undo recording when changing through PropertyTree

[Maciej Paluszek]

For some reason when drawing serializable object (MonoBehaviour and ScriptableObject) through PropertyTree, changes made on AnimationCurve are not saved with Undo. Changes to other types are saved as expected.

In attachement I’ve added files with reproduction.

TestAnimationCurve - simple MonoBehaviour with AnimationCurve and int

TestAnimationCurveEditor - simple editor window that draws TestAnimationCurve with PropertyTree from selected GameObject
