 @ocean90: in [attachment:30988.4.diff]:

 * Restore `parse_post_values()` as `unsanitized_post_values()`
 (incorporating feedback above), since I just realized it is needed by
 #30936; use `array_key_exists` instead of `isset` to account for `null`
 values; improve PhpDoc: https://github.com/xwp/wordpress-
 develop/commit/23523a9c945c269d5f70b83beb3620cc304e0089
 * Add unit test for `WP_Customize_Manager`: https://github.com/xwp
 /wordpress-develop/commit/2fb9fd4d7b1f2d0d19a7b185b14ba800f6d68e72
