When using a responsive image with srcset the with and height attributes are not available in twig. Both of them are
NULL When an image is uploaded that is too small images are stretched or blown up as described in this post: https://medium.com/@MRWwebDesign/responsive-images-the-sizes-attribute-and-unexpected-image-sizes-882a2eadb6db
Being able to set a with equal to the pixelsize of the image would solve this issue. How can I make these attributes available for twig?
