Details:

The HTML picture element provides a way to specify multiple image source
candidates. This can be used to e.g. show SVGs on browsers that support it,
and PNG fallbacks everywhere else:

<picture>
<source type="image/svg+xml" srcset="logo.svg" />
<img isrc="/img/logo.png" srcset="logo.png 1x, ***@2x.png 2x, ***@3x.png
3x" alt="logo" />
</picture>

If I invoke `wget -r` on a site with this markup however, wget only fetches
the src and srcset, not the picture source candidates.

Follow-up Comment #1, bug #55087 (project wget):

Wget2 already supports it.

Eventually we backport it to Wget1.x.
