Problem: JSON_OVERLAPS treats unequal nested arrays as equal when only one parser reaches the array end. Requiring both ends also exposes a cleanup issue: scanning ']' moves stack_p to the parent, so skipping the current level consumes parent elements. This misses the common [2] in [[1],[2]] and [[],[2]], and can skip unequal recursive elements. Fix: Require both parsers to reach JST_ARRAY_END. Remember their array levels before comparing and skip to those saved levels after completed comparisons and mismatches, preserving parent siblings. Explain why the saved levels are needed. Add regression coverage for both argument orders, unequal lengths, empty arrays, recursive comparisons, type mismatches, array order and a later common object member.

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:
https://mariadb.com/docs/release-notes
Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
Help
