It doesn't expose the highest resolution available for the photo

Probably because of the srcset attribute. In my case it seems like the src attribute holds the highest resolution.

Removing the srcset attribute doesnt solve it, because it gets recreated once removed, in my testing.
Creating a new image element with the same attributes, except the srcset attribute, seems to do the trick.
