The last image in a srcset isn't parsed

On the same retail site as issue 22, the last img in a srcset is not parsed properly.

The affected img tag:

<img sizes="(min-width: 1280px) 816px, (min-width: 1024px) 62vw, 100vw" srcset="https://site.tld/image/w=375,h=234,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 375w, https://site.tld/image/w=568,h=355,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 568w, https://site.tld/image/w=750,h=469,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 750w, https://site.tld/image/w=816,h=510,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 816w, https://site.tld/image/w=1125,h=703,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 1125w, https://site.tld/image/w=1632,h=1020,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 1632w, https://site.tld/image/w=2448,h=1530,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg 2448w" loading="eager" src="https://site.tld/image/w=375,h=234,fit=scale-down,q=75,f=auto,sharpen=0.5/images/3/2_663280-201x522.jpeg" width="375" height="234">
