 * The full-width images on my WordPress site in the classic block editor appear
   blurry, and I think I’ve nailed down the source of the issue. It seems that there
   are some automatic responsive image stylings that set the image width at specific
   viewport widths. For example, the one that’s causing my full width pictures to
   look blurry is this query:
 * sizes=”(max-width: 640px) 100vw, 640px”
 * Is there any way to override these settings in the understrap theme? The issue
   doesn’t happen when I hardcode the image into the page’s php file, but I would
   like to be able to easily replace the image in the block editor without touching
   the theme editor. I tried to add my own “sizes” attribute in the html in the 
   code editor, but I get an error message saying “This block contains unexpected
   or invalid content”.
