https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=28561 --- Comment #5 from Marcel de Rooy <m.de.rooy@rijksmuseum.nl> --- NOTE: Although this patch significantly reduces the number of warnings on the collapse.

[2021/06/14 13:06:59] [WARN] DBIx::Class::ResultSet::_construct_results(): Unable to properly collapse has_many results in iterator mode due to order criteria - performed an eager cursor slurp underneath.
