Keep wrapper with empty alt

[alexander-litvinovich]

Why image with empty alt, aren't wrapped up in <figure />?
The <figure /> could be without <figcaption />, but when wrapper disappears, the layout could break.

It would be good if the wrapper was presented even with an empty alt.

It's correct to create figures without captions: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/figure
