Context

When use_sidenotes is true and footnotes are converted to sidenotes, inline elements within the footnote content are stripped. When use_sidenotes is false, the inline elements show up as-is within the footnote. This means you can't even have bold or italics in sidenotes, which seems like a needless restriction.

Proposal

I'm not familiar with the details of Sphinx or Docutils, so I'm not sure how big of a task this is. As far as I can tell it's because of the call to astext() here:
