Editor bug in CinemachineImpulseEnvelopePropertyDrawer

Hey, so I've encoutered a bug when creating a ScriptableObject version of CinemachineImpulseSource.
Class is basically this:

Code (CSharp):

1. [CreateAssetMenu(fileName = "new Cinemachine Impulse Asset", menuName = "Cinemachine/Cinemachine Impulse Asset")]
2. public sealed class CinemachineImpulseAsset : ScriptableObject {
3.  
4.     [CinemachineImpulseDefinitionProperty]
5.     public CinemachineImpulseDefinition definition = new CinemachineImpulseDefinition();
6. }

Just a ScriptableObject housing an Impulse Definition.

The problem is when multi-selecting these assets, the "Time Envelope" settings are applied to all selected assets based on the first. Instead of showing a "mixed" value in Inspector.
I've nailed this down to the "CinemachineImpulseEnvelopePropertyDrawer" property drawer. Specifically line 85:

Code (CSharp):

1. EditorGUI.PropertyField(rect, timeProp, timeText);
2. timeProp.floatValue = Mathf.Max(timeProp.floatValue, 0);

I guess you need to listen for changes made before setting timeProp.floatValue

Anyway, temp solution is to disallow multi-object editing.
Let me know if you need a full bug report submitted
