Twenty Twenty-One: PHP Warning when attachment meta is missing

[domainsupport]

When an attachment doesn’t have “width” or “height” meta (for whatever reason), the following PHP error is shown …

PHP Warning: Undefined array key "width" in /wp-content/themes/twentytwentyone/inc/template-functions.php on line 460

I think that this line in template-functions.php be changed from …

<?php
if ( $meta['width'] && $meta['height'] ) {

… to …

<?php
if ( isset($meta['width']) && $meta['width'] && isset($meta['height']) && $meta['height'] ) {

Sorry, I did try to see if there was already a ticket. Missed that. My bad.
