Pin ls stops traversing recursive pins after hitting a direct pin

[Stebalien]

We should avoid re-emitting these directly pinned blocks but we still need to continue traversing the tree. This needs a test to be considered fixed.

Regression from #6493.

@Stebalien Does this also mean that this case isn't covered by the current test set? I am guessing this was caught via manual testing as the tests passed in #6493.

[Stebalien]

It is not covered by the current test set. I haven't actually reproduced this issue, I just happened to re-read the code...

[lanzafame]

Can we add to this issue that the fix includes a test to cover this case?

[lanzafame]

Just in case someone else picks up the fix.
