 If you append numbers in any post/page URL (after a slash) it still
 returns a valid HTTP 200 even if there are no pages. The limit is
 9223372036854775807 page number.

 If you append anything above 9223372036854775807 (like
 9223372036854775808) then it automatically redirects to
 9223372036854775807.

 9223372036854775807 happens to be the limit of a signed 64-bit integer.

 Example URLs to test:
 1. https://wordpress.org/news/2019/12/wordpress-5-3-1-security-and-
 maintenance-release/9223372036854775807
 2. https://wordpress.org/news/2019/12/wordpress-5-3-1-security-and-
 maintenance-release/9223372036854775808

 You can try this with any WordPress based website with any theme. This
 issue also happens with WooCommerce product pages. I've tested it with
 5.2.x, 5.3, and 5.3.1 but further testing is required to know how many
 WordPress versions have the same issue.

 Expected result should be an error message (like 404) if the page number
 doesn't exist.
