 It appears that some images added with the gutenberg editor (no updates
 since June) now have height and width attributes being dynamically added
 following the new loading attribute.

 I updated locally only so far.

 This is the previous img element being displayed in the browser:

 {{{
 <img src="https://www.brothersmoving.local/wp-
 content/uploads/2020/06/AdobeStock_230714251_Preview.jpeg" alt="Adobestock
 230714251 Preview" class="wp-image-8050"
 srcset="https://staging.brothersmoving.ca/wp-
 content/uploads/2020/06/AdobeStock_230714251_Preview.jpeg 1000w,

 /AdobeStock_230714251_Preview-300x134.jpeg 300w,
 https://staging.brothersmoving.ca/wp-content/uploads/2020/06
 /AdobeStock_230714251_Preview-768x344.jpeg 768w" sizes="(max-width:
 1000px) 100vw, 1000px">
 }}}


 This is it now:

 {{{
 <img loading="lazy" width="1000" height="448"
 src="https://www.brothersmoving.local/wp-
 content/uploads/2020/06/AdobeStock_230714251_Preview.jpeg" alt="Adobestock

 /AdobeStock_230714251_Preview-768x344.jpeg 768w" sizes="(max-width:
 1000px) 100vw, 1000px">
 }}}

 These are the new attributes being added:

 {{{
  loading="lazy" width="1000" height="448"
 }}}
