    Description

      Since upgrading from 10.2 to 10.5.13 queries using IN clauses with many values have performance issues.

      This is the same issue reported under MDEV-24117 whichi s fixed in 10.5.8. Even though it's fixed in 10.5.8, I can reproduce the same issue in 10.5.9 and 10.5.13 with the attached mariadbbug.sql in the MDEV-24117.
