* `paginate_links` doesn't use the provided `format` when the page is `1`.
* This is great for the main query as it removes the extra query params
* making the URL shorter, but in the case of multiple custom queries is
* problematic. It results in returning an empty link which ends up with
* a link to the current page.
*
* A way to address this is to add a `fake` query arg with no value that
* is the same for all custom queries. This way the link is not empty and
* preserves all the other existent query args.
*
* @see https://developer.wordpress.org/reference/functions/paginate_links/
*
* The proper fix of this should be in core. Track Ticket:
* @see https://core.trac.wordpress.org/ticket/53868
*
* TODO: After two WP versions (starting from the WP version the core patch landed),
* we should remove this and call `paginate_links` with the proper new arg.
