 Priority:  normal         |  Milestone:  Awaiting Review
Component:  Media          |    Version:  5.8

 In preparation for WP 5.8 I tested the new filter
 'image_editor_output_format' as described. It worked with WP5.8-RC4 from
 2021-07-17. No Problems at all. After the update to WP5.8 the 2021-07-21
 the images are no longer converted. Tested on local site, staging site and
 productive site. The used code is:
 {{{#!php
 <?php
 add_filter( 'image_editor_output_format', function( $formats ) {
         $formats['image/jpeg'] = 'image/webp';
         return $formats;
         }
 );
 }}}

 The servers environment is show in the attached file of the wp health
 check. No server setting was changed between the test and the update. I
 double checked to attach the code to a mu-plugin, a separate plugin and
 the functions.php.

 The webp support is great, so I wanted to use it immediately.

 Best Regards
 Martin
