ViewChild(MyDirective) results in undefined when MyDirective is declared in Sub-Module

Which @angular/* package(s) are the source of the bug?

core

Is this a regression?

No

Description

When my-directive is used in app-root and the directive is declared in a sub-module (library) the viewchild is undefined.

When declaring a directive in the same module where the app-root is declared everything works.
