[Bug 1571363] [NEW] Installing with recommended packages does not query down anymore on already installed dependencies

[Sworddragon]

Public bug reported:

I'm using Ubuntu 16.04 with apt 1.2.10ubuntu1 and on installing with
recommended packages for example by using the option "--install-
recommends" normally apt installs the recommended packages of the
specified package and the recommended packages of the dependencies at
any level. But at the latter I'm noticing if such a dependency was
already installed without installing its recommended packages apt will
not query anymore down to the recommended packages of this dependency.
This behavior does also break packages that provide only possibly too
minimal dependencies and relying more that the user also installs the
recommended packages like in this case:
