 In Imagick, WordPress now supports saving lossless WebP images when the
 source is a lossless WebP image. 🎉

 This happens [https://github.com/WordPress/wordpress-
 develop/blob/f17f4f5f7e474e2c0bb77ace02aaf44fccd8362c/src/wp-includes
 /class-wp-image-editor-imagick.php#L208 inside the Imagick editor in
 `set_quality`].

 The filter, `wp_editor_set_quality`, applies before this is run, in
 [https://github.com/WordPress/wordpress-
 develop/blob/f17f4f5f7e474e2c0bb77ace02aaf44fccd8362c/src/wp-includes
 /class-wp-image-editor.php#L241 the parent class].

 This means that if a WebP is detected as Lossless, it isn't possible to
 override lossless thumbnailing with `wp_editor_set_quality`.

 WordPress should respect the `wp_editor_set_quality` filter's override,
 [https://developer.wordpress.org/reference/hooks/wp_editor_set_quality/
 unless `set_quality()` is run manually].
