Serialization fails on an serializable class defined internally to a wrapped generic class



How to reproduce:
1. Open user attached project
2. Enter playmode
* - Notice 'All good' in console
3. While in playmode, edit the SerializationTest.cs (comment/uncomment line 32)
4. Return to editor to force recompilation
* - Notice 'Single instance null' in the console

Expected behaviour: The nested class inside a generic class wrapper does not lose reference to the public member when serializing/deserializing
Actual behaviour: The reference to the classRef remains, but the classRef.SingleInstance has been replaced with null

Notes: If the classes, both GenericClass and InternalClass, are not marked Serializable but instead extend ScriptableObject, the problem remains.

Reproduced on: all versions
Reproduced on: .NET 3.5 and .NET 4.5

    Resolution Note:

    This particular case has been investigated thoroughly and we have decided, in the interests of protecting the stability and features of Unity for users that rely upon the affected versions, to not address this fix for the time being. We understand that this will cause problems for some users, and so may address in a future version.
