Unable to represent an entity that owns multiple one-to-one relationships

[ascott18]

The following used to work automatically before 513db25

public class Parent {
  public int ParentId;

  public Child1 Child1;
  public Child2 Child2;
}

public class Child1 {
  [Key, ForeignKey("Parent")]
  public int ParentId;
  public Parent Parent;
}

public class Child2 {
  [Key, ForeignKey("Parent")]
  public int ParentId:
  public Parent Parent;
}

It no longer does after that commit.

Adding explicit config results in a codegen exception (due to ParentId owning multiple inverse navigations, I think)

public class Parent {
public int ParentId;
[InverseProperty(nameof(Child1.Parent))]
public Child1 Child1;

[InverseProperty(nameof(Child2.Parent))]
public Child2 Child2;
}
