 * All widths are specified in attr srcset, but W3C Validation throws error
    Error:
 * `Bad value data:image/svg+xml;charset=utf-8,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.
   w3.org%2F2000%2Fsvg%27%20width%3D%271280%27%20height%3D%27720%27%20viewBox%3D%
   270%200%20194%2069%27%2F%3E for attribute srcset on element img: No width specified
   for image data:image/svg+xml;charse…0%200%20194%2069%27%2F%3E. (When the sizes
   attribute is present, all image candidate strings must specify a width.)`
 * Code:
    `<img class="alignnone size-full wp-image-46808 demilazyload" src="https://
   planet-mcpe.com/wp-content/uploads/2021/06/minecraft-1-17.jpg" alt="Обложка Майнкрафт

 * Is it because of the symbols in pic’s path? Is there any way to fix it in the
   settings, or do i have to alter plugin’s code now?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fwebp-express-validation-error%2F%3Foutput_format%3Dmd&locale=en_US)
