What I did:
I used [^1]
notation in a Markdown component.
What’s not working:
It’s rendered as a link that does a full-page reload. Likewise for the return link at the end of the footnote.
This might be okay on pages where you’re willing to lose user input, or otherwise navigate out of the current page.
Workaround:
Use Unicode superscript characters instead. These do not render as links.
