Products don't pick up properties from recursive module dependencies coming in via an Export item

Let's assume we have a module M1 and a module M2. M1 depends on M2 and M2 sets certain properties.
Let us further assume we have products A and B. If B has a dependency on M1, the properties set in M2 will come in as expected. However, if B has a dependency on A and A exports a dependency on M1, the properties set in M2 will not be present in B.
The behavior should be the same.
