Bug: undefined srcset with use-picture

[TheAlexLichter]

Heyho 👋

The following code will result in an undefined undefined value for the srcset of the source slot.
Using a string instead (:srcset="'https://googlechrome.github.io/samples/picture-element/images/butterfly.webp'") is a workaround to avoid that issue.

    <v-lazy-image
      use-picture
      srcset="
        https://cdn-images-1.medium.com/max/800/1*xjGrvQSXvj72W4zD6IWzfg.jpeg,
        https://cdn-images-1.medium.com/max/1200/1*xjGrvQSXvj72W4zD6IWzfg.jpeg 1.5x,
        https://cdn-images-1.medium.com/max/1600/1*xjGrvQSXvj72W4zD6IWzfg.jpeg 2x
      "
      src="https://cdn-images-1.medium.com/max/800/1*xjGrvQSXvj72W4zD6IWzfg.jpeg"
    >
      <source
        type="image/webp"
        srcset="https://googlechrome.github.io/samples/picture-element/images/butterfly.webp"
      />
    </v-lazy-image>

That's weird... any ideas why it happens? They should be equivalent
