 In certain edge cases it is possible that the keys `width` or `height` can
 be null or not set inside of `wp_get_missing_image_subsizes()`.

 I got that warning in the sentry installation of my project. While this
 was a rare occurrance it did happen.

 I propose to add a ternary operator to check and sanitize here like done
 at other places.

 PR on Github.
