Expendable Army does not affect Offering maximum count

The passive skill "Expendable Army"
(which increases the maximum number of temporary minions)
does not seem to affect Offerings.

Offerings are explicitly described as minions,
and their maximum number can be successfully increased by:
- the support gem "Overcap"
- the unique amulet "Idol of Uldurn"

However, allocating "Expendable Army" does not increase
the number of active Offerings for any of the three types:
Bone Offering, Soul Offering, or Pain Offering.

Since Offerings are both minions and temporary entities,
could you please confirm whether this behavior is intended,
or if this might be an oversight in how the passive is applied?
