------------------------------+-----------------------
 Several core tests added in the past few releases of WordPress (mostly
 related to lazy-loading) have been making use of the main query global
 (`$wp_the_query`, different from `$wp_query`) and modifying it in tests.

 It was assumed that that global was being reset between tests similar to
 other query loop-related globals, but in https://github.com/WordPress
 /wordpress-develop/pull/4799#issuecomment-1629114720 it was discovered
 that the `$wp_the_query` global is not reset between tests, which is
 unexpected behavior and caused problems with the tests in that PR.

 This should be fixed so that the global is reset similar to the other
 related globals like `$wp_query` and `$wp`. Similar to the regular
 WordPress bootstrap process in `wp-settings.php`, the test suite should
 ensure that `$wp_query` and `$wp_the_query` point to the same `WP_Query`
 instance.
