**List of steps to reproduce** (step by step, including full links if applicable):
* Go to https://ko.wikipedia.org/wiki/Special:Contributions/2001:2d8::/32
or https://ko.wikipedia.org/wiki/Special:Contributions/2001:e60::/32
* Go to next page where the link indicates 'see previous 100 entries'
**What happens?**: Sometimes, when loading IPv6 CIDR range in Korean Wikipedia, the database error occurs instead of showing the actual contributions list. Either MediaWiki internal error message or Database query error occurs with the message "Wikimedia\Rdbms\DBQueryError" (Fatal error)
Note: Turning off the CIDR range related gadgets will not resolve the problem.

**What should have happened instead?**: There should be normal contributions list for the CIDR range.
**Software version (if not a Wikimedia wiki), browser information, screenshots, other information, etc.**:
