Client Script: Edit page onChange doesn't fire when selecting "-None-" value.

Client Script: Edit page onChange doesn't fire when selecting "-None-" value.

I have a client script using the onChange event on the standard edit page that updates another field based on value selected in a pick list.  This works great except I just realized when you select the "-None-" option in the pick list if you wanted no value set then it doesn't fire the event... which means I have no feedback to know the field is set empty so I can update this other field appropriately.

This definitely feels like it shouldn't be that way and a bug/oversight unless I'm missing something?  If you are setting a fields value from something to nothing then I'd consider that a "change" for sure.  As a work around I suppose I can/have to create another client script on the onSave event with the logic that checks if that field is set empty and if so then update the other field.
