WordPress post editor pagination uses inconsistent URL variable to rest of site

[roballshouse]

/wp-admin/edit.php

uses functions in class-wp-list-table.php

Which uses
$current_url = set_url_scheme( 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] );

While all other pages use
WP_SITE_URL

Thus, when in the post editor, the "Next page" goes to (in my case) https://127.0.0.1:8090/wp-admin/edit.php?paged=2, instead of to <my_url>/wp-admin/edit.php?paged=2 like the rest of wp_admin

Welcome to Trac, @roballshouse, and thank you for the report!

This ticket could use some ​testing steps that would make reproduction of the issue more straightforward, so I've added the appropriate keyword.

Testing Instructions

Setup a WP environment with separate SERVERHTTP_HOST? values (such as 127.0.0.1) and WP_SITE_URL value (such as a custom domain, pointing to the host)

Navigate to Post editor, and look at "Next Page" URL

Steps to Test

1. Navigate to <server>/wp-admin/edit.php on remote system using domain (e.g. ww.myblog.com/wp-admin/edit.php)
2. Attempt to click <Next Page>
3. Fail due to invalid URL (such as ​https://127.0.0.1:8090/wp-admin/edit.php?paged=2)
