requested to merge issue/bootstrap_barrio-3323096:sebastien_gicquel-5.x-patch-17803 into 5.x
There is no media query to handle the
mediaQuery: 'all and (max-width: 33.99em)' case.
33.99em it is the fallback image style that is used in the Responsive image styles and that seems to be a problem. The image is not loaded in webp format for example.
