There is no probably no limit, and your ticket might actually prompt them to add one due to the performance issues it causes. Although wikia users aren't as obsessed with reports as wikipedia users are. Personally, I would never manually review over 5000 reports.

It might  be a non-issue because fewer users have bot rights and are able to see batches of 5000 reports at any given time. Also, that patch was actually deployed to mediawiki last year, and wikia hasn't yet found the need to backport it.
