ArgumentOutOfRangeException for split query with owned types

[AndriySvyryd]

Query:

context.Set<Root>()
    .AsSplitQuery()
    .Include(e => e.OptionalChildren)
    .OrderBy(e => e.Id)
    .Single(r => r.AlternateId == Fixture.RootAK);

Root.RequiredSingle and Root.RequiredSingleAk are owned.

Are owned objects mapped to different tables?

[AndriySvyryd]

Root.RequiredSingle is table-splitting
Root.RequiredSingleAk is mapped to a different table

@smitpatel What's the servicing-consider status of this?
