 In #44427 the feature to lazy load images by default was added.

 The code uses regex and hence there are some edge cases which can
 complicate.

 One such case is adding


 {{{
  loading=lazy
 }}}

 with space before 'loading' in the alt value.

 This can be done in the block-editor by selecting the image and adding the
 above in:

 Image settings > Alt text (alternative text) box

 This is allowed in HTML.

 When this is done, the regex thinks that the image tag has a lazy loading
 attribute and doesn't add it.
