EntityComponent not getting values when being deserialized

1. Attach both components to an entity and set the "Asset" property to a prefab.
2. Save
   Two things you'll notice:
3. The prefab doesn't get linked into the build when using MyStoryGameMode1, but does with MyStoryGameMode2.
4. The prefab asset ID is properly saved into the asset file (which means the issue is only for deserialization).

  //
  // MyStoryGameMode1 always has null values, even though the values are set inside the stride asset files.
  //  - You can also test this by noticing the Prefab asset inside the GameStudio editor doesn't get linked into the build,
  //    where as it does when using MyStoryGameMode2.
  //
  [DataContract]
  public struct ClassReference
  {
      public Prefab Asset { get; set; }
  }
  [DataContract("MyGameMode", Inherited = true)]
  public abstract class MyGameMode : EntityComponent
  {
      [DataMember]
      public ClassReference PlayerClass { get; set; }
  }
  public abstract class MyGameMode<T> : MyGameMode
  {
  }
  public abstract class MyNetGameMode<T> : MyGameMode<T>
  { 
  }
  // Doesn't de-serialize
  public class MyStoryGameMode1 : MyNetGameMode<object>
  {
  }
  // Does de-serialize because we changed the base.
  public class MyStoryGameMode2 : MyGameMode<object>
  {
  }

Reproduce the issue with the MyStoryGameMode1 and MyStoryGameMode2 class hierarchies, attaching both components and assigning a prefab to ClassReference.Asset before saving. Compare the deserialization paths for the inherited generic EntityComponent types and verify that MyStoryGameMode1 restores the prefab asset ID and links the prefab into the build, matching MyStoryGameMode2.
