Hello @SerTetora,
this is not a bug, so I'll convert it to a discussion.
The issue is that you're missing the markdown attribute in the figcaption:

<figure markdown>
<figcaption>Image caption[^1]</figcaption>

->

<figure markdown>
<figcaption markdown>Image caption[^1]</figcaption>

Each tag in the "chain" needs to be marked as Markdown content, otherwise, HTML tags inside of HTML-markdown tags are rendered as raw HTML not Markdown.

Thank you for the explanation, I was not aware of that.
