Comment (by donmhico):

 I've attached a new patch
 [https://core.trac.wordpress.org/attachment/ticket/48027/48027.1.diff
 48027.1.diff], that basically change the `user_id` property to `int`
 before the comment object is returned. Although i'm not if this is good
 enough. Its also possible to convert it to `int` before it is added to
 cache using `wp_cache_add`. Let me know your thoughts.

 I've added some unit tests and as well as change some existing ones to
 reflect the change. It might be good to create a `dev-note` regarding this
 as existing themes / plugins might be using `===` before and those will
 break since the patch will change the `user_id` from `string` to `int`.
