> Unpack the attached test case.  It is a rather large multimodule project which looks
like the following:
> {code}
> test:i:jar:1 (0; enabled)
>   test:c:jar:3:compile (1; enabled)
>     test:b:jar:2:compile (2; enabled)
>   test:e:jar:2:compile (1; enabled)
>     test:c:jar:2:compile (2; disabled)
>       test:b:jar:1:compile (3; disabled)
>         test:a:jar:1:compile (4; disabled)
>     test:h:jar:1:runtime (2; enabled)
>       test:g:jar:1:runtime (3; enabled)
>         test:a:jar:2:compile (4; disabled)
>   test:f:jar:1:compile (1; enabled)
>     test:e:jar:1:compile (2; disabled)
>       test:c:jar:1:compile (3; disabled)
>     test:d:jar:1:compile (2; enabled)
>       test:c:jar:2:compile (3; disabled)
>         test:b:jar:1:compile (4; disabled)
>           test:a:jar:2:compile (5; disabled)
> {code}
> There is a dependency chain I1 -> E2 -> H1 -> G1(runtime) -> A2
> During version resolution, the G1->A2 dependency is dropped due to checkScopeUpdate
in favor of upgrading the version of B1 -> A1 into B1 -> A2, since it has compile scope.
> The B1 -> A2 dependency is later suppressed because C3 has a "nearer" dependency on
B2, tossing B1.  So A2 is lost even though there is a legitimate need for it from G1.
> To reproduce:
> {code}
