I do not know, yet.

We are still using ZODB 3.4 and multi-database support was added
in ZODB 3.6.

But, I expect it is a Zope bug because both of your mounts
could (and almost surely should) use the same database and connection.

Both Zope and ZODB use the same collector. ZODB bugs get
the category "database".

I would file the bug report in this way (Zope collector
with category "database") even if it is not a ZODB error
(at least it is database related).

I do not know -- as I did not yet analyse such a problem.
