Include_relative liquid tag inside collection doc doesnt work

I’m trying to use include_relative liquid tag inside one of my collections document but it is giving me an error:
Liquid Exception: Could not locate the included file
Is this related to this issue? If true, is there any estimation on when the issue is going to be fixed?

I found that it happens when I’m putting all my collections inside a directory with collections_dir.

If I don’t use collection_dir and use normal collections, it doesn’t give me error.

Since I believe this is a bug, I reported it here.
