Comment:

 Hi there, welcome to WordPress Trac! Thanks for the report.

 Some context from
 [https://wordpress.slack.com/archives/C02RQBWTW/p1606844703391900 #core on
 Slack]:
 > `add_image_size()` should be called on the `after_setup_theme` action
 hook. It's not clear from the inline documentation, but there's a
 [https://developer.wordpress.org/reference/functions/add_image_size/#comment-296
 comment on the developer hub detailing that].

 Let's use this ticket to clarify the inline documentation :)
