i did a patch for this issue 1.5 years ago, but i never committed it

the method i used, was to fetch more records than needed from zebra
(like 40 bibs, not 20)

its obviously not a perfect solution, there is a chance that all 40 bibs
fetched might be hidden, and you would still end up with 0 bibs displayed

^^despite that, in real life this patch worked well

the only other solution, afaik, is to keep doing zebra queries until one page
of non-hidden bibs is accumulated

i'll upload my patch soon...
