lazy-load-xt no picture are loaded

Hello

I'm using the lazy-load-xt plugin with the responsive extension.
In Some cases no pictures are loaded. But why?



  1. <img class="img-responsive" sizes="(min-width: 36em) 50vw, 100vw"
                                    data-srcset="http://lorempixel.com/375/275/ 375w, http://lorempixel.com/350/350/ 480w, http://lorempixel.com/384/384/ 768w, http://lorempixel.com/720/480/ 800w" alt="a picture" />
