 Dear Developers,

 I tried to put an image into one of my posts encoded with base64. The
 image is encoded from PNG to Base64 using macOS
 {{{
 base64 -i input.png -o output.png.txt
 }}}
  command.

 The image converted and successfully edited in the related post image
 block by entering HTML editor and replaced the img src="" with the
 following:

 {{{
 <figure class="wp-block-image aligncenter"><img
 src="data:image/png;base64,<base64 long string>" alt="Alternate text"
 /></figure>
 }}}

 When I switched back to preview mode, the image successfully displayed in
 the editor, however the post when published is broken.

 I have some screenshots from my blog site as well as the image as base64
 file.
