I'm experiencing some odd behavior when changing the PropertySetMode at runtime.
I have two object types: MyTestClass1 and MyTestClass2. MyTestClass1 has a writeable property IntProp and MyTestClass2 has a readonly property IntProp. If I start in Intersection mode with Item = List<Object> { myTestClass1Obj1, myTestClass1Obj2 } everything works properly. If I then change to PropertySetMode None with Item = myTestClass2Obj, the editor for IntProp will be writeable even though IntProp on myTestClass2Obj has no public setter.
See runnable test case below. I am running 2015.2.728
