HTML <picture> Element not returned as image link from srcset

[contendaClara]

The image link from the srcset is not returned in the markdown return in the <picture> html element. I expect it to be returned like if the image src was in the <img> html element.

Code snippet example:

import html2text

html = """
<section>
    <h1>Poorly drawn lines comics</h1>
    <picture>
        <source
            sizes="(min-resolution: 4dppx) and (max-width: 700px) 50vw, (-webkit-min-device-pixel-ratio: 4) and (max-width: 700px) 50vw, (min-resolution: 3dppx) and (max-width: 700px) 67vw, (-webkit-min-device-pixel-ratio: 3) and (max-width: 700px) 65vw, (min-resolution: 2.5dppx) and (max-width: 700px) 80vw, (-webkit-min-device-pixel-ratio: 2.5) and (max-width: 700px) 80vw, (min-resolution: 2dppx) and (max-width: 700px) 100vw, (-webkit-min-device-pixel-ratio: 2) and (max-width: 700px) 100vw, 700px"
            srcset=" https://pbs.twimg.com/media/FbVo3fiUcAAYytB?format=jpg&name=smal 640w, 
                https://pbs.twimg.com/media/FbVo3fiUcAAYytB?format=jpg&name=medium 828w, 
                https://pbs.twimg.com/media/FbVo3fiUcAAYytB?format=jpg&name=large 1400w" />
        <img alt="" />
    </picture>
    <p>
        This is one of my most favorite recent comics. Comes in print too. I want it for my home.
    </p>
</section>
"""
md = html2text.html2text(html)
print(md)

Actual Output:

# Poorly drawn lines comics

This is one of my most favorite recent comics. Comes in print too. I want it
for my home.

Expected Output:

• includes the image link (though I'm not particular for which one)
• same result as if using the <img> html element

# Poorly drawn lines comics
