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. Please feel free to add these steps, or the keyword may also signal other contributors to do the same.

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)
