Zebra facets usage was implemented here:

If you are using Zebra's native facets implementation (use_zebra_facets) on a recent Koha version (i.e. using DOM indexing) then your system is not using maxRecordsForFacets, but this configuration:
As you can see, it is pulling the facets from the first 1000 records in the result set. You could definitely try lowering it down to something reasonable (in your terms).

Sorry for the mistake, I had my eyes on that bug a while ago and was sure there was lots of interest in the feature, so assumed it was already in master!
Good luck.
