Comment (by darshitrajyaguru97):

 Tested the patch locally and confirmed the new `wp_reset_vars()` tests are
 passing successfully.

 Environment:

 * WordPress: trunk
 * PHP: 8.2.29
 * Database: MySQL
 * PHPUnit: latest Core test suite

 The added coverage looks solid overall, especially around documenting the
 current `empty()` behavior for values like `'0'` and `''`.

 A few additional edge cases may be worth considering, either in this patch
 or a potential follow-up:

 * `false`
 * `0` (integer)
 * `null`
 * array values

 Additionally, in `tear_down()`, previously unset globals could potentially
 be restored using `unset()` instead of assigning `null`, which may help
 preserve the original global state more accurately.

 Patch tests successfully.
