Incorrect results when selecting reference collection navigation chain on keyless entity

[smitpatel]

Additional scenario of #21607

return AssertQuery(
                async,
                ss => ss.Set<OrderQuery>().Where(ov => ov.CustomerID == "ALFKI").Select(ov => ov.Customer)
                    .OrderBy(c => c.CustomerID)
                    .Select(cv => cv.Orders.Where(cc => true).ToList()),
                assertOrder: true,
                elementAsserter: (e, a) => AssertCollection(e, a),
                entryCount: 6);

OrderQuery is keyless. Customer is reference navigation. Putting a collection join on Customer causes issue since customers are repeated for different values of OrderQuery and we don't have a way to identify different OrderQuery results.
