 [https://core.trac.wordpress.org/attachment/ticket/53232/53232.10.diff
 53232.10.diff] refreshes the previous patch with the following updates:

 - Fix failing tests.
 - Add dedicated tests for `wp_img_tag_add_decoding_attr()`.
 - Change `false === strpos()` to `! str_contains()`, which was polyfilled
 in WordPress 5.9.
 - Fix some documentation alignment issues.
 - Adjust the documented type of `$value` for the
 `wp_img_tag_add_decoding_attr` filter.
   - This was previously `string|bool`, but is documented to be
 `string|falsey`. Reasonable falsey values for a callback for this filter
 would be `''`, `false` or `null`. The type for `$value` has been adjusted
 to `string|false|null`.
 - @peterwilsoncc has applied these changes to
 [https://github.com/WordPress/wordpress-develop/pull/2409 PR 2409].

 @adamsilverstein can you take a look at the above changes and let me know
 your thoughts?
