Issue description

When a node inherits from a scene and that scene has a property that isn't set to default, the inherited node will also show a revert button for that property even though the button does nothing.

Steps to reproduce

• Have a scene a, and a scene b which inherits from a
• Set a property in a to something other than default
• Open b and make sure that property is the same as a
• The property will still show a revert button even though there's nothing to revert, and it does nothing.
