It seems different optimization was applied. Rowid filtering is an optimization available from MariaDB 10.4.3+, so please disable rowid_filter
optimizer switch, and re-issue the query.
SET SESSION optimizer_switch='rowid_filter=off';
, then issue the query.

Thanks! I need to investigate why a new optimization is degrading performance, but works as workaround.
