Problems with Sharing between companies?

I am running on ERPNext: v13.0.0 (version-13) and Frappe Framework: v13.0.1 (version-13).

Multiple companies setup.

User A with company A creates Item A.
User B with company B cannot see Item A. OK

User A shares item A with user B for read. User B can see it. OK.
User A tries to share item with user B for write. B can still only see it. no write possible. No print view possible. NOT OK

Is there something wrong in my setup or shall I raise a bug?

If userB is given the system manager role, write and print is possible. But obviously this is not acceptable…

seems like the update to 13.1 had some fixed/improvements in the area of sharing. write share is now working.
print right seems to be currently not possible to be shared. I am looking into code fix/hack…
