Media Grid does not respect taxonomy URL parameters

[mclaurent]

The media items are correctly filtered on the list page but the grid view does apparently not take the taxonomy filter into account.

The list view was fixed in https://core.trac.wordpress.org/ticket/30584

Environment

• WAMP
• WP 4.9.5
• Twenty Seventeen
• PHP 7.1
• 10.0.19-MariaDB

Steps to reproduce

Add a category to the media by adding this to functions.php

<?php
add_action( 'init', 'jw_tax' );
function jw_tax(){
        register_taxonomy( 'media_cats', 'attachment', array(
                'label' => __( 'Media Categories', 'jw' ),
                'hierarchical' => true,
        ));
}

Same steps as the other ticket.

1. Upload an attachment via Media > Add New
2. Edit the attachment and add to new category
3. Add more media but don't attach to the category.
4. Go to the Media > Media categories, click on the number in the final column (1)
5. You are redirected to the grid view of the media section. Note all items are showed.
6. Switch to the list view and see the filter is applied correctly.

Interesting.

I could not reproduce on my setup. The URL is also different being /wp-admin/upload.php?media_cats=one&post_type=attachment&mode=list. What am I missing?

Figured it out. My custom taxonomy had 'query_var' => false which was preventing it from applying in the query. Thank you for double-checking!
