When only the `page.summary` is shown in a `section`, its `footnote-reference`s are shown but the links are broken if the site is configured with `bottom_footnotes = true`.

I believe it would make sense to strip the footnote references altogether from the `summary` in such cases. Maybe the `markdown` filter could take an additional optional parameter to avoid rendering footnotes altogether?

Actually it looks like some code is supposed to be doing just that:

Yet I still see the `<sup class=”footnote-reference”>` in my `summary`.

Found the issue, submitted a PR:

> <https://github.com/getzola/zola/pull/2962>
>
> This commit updates and fixes the regular expression to find and delete footnote… references in the pages' summaries.
> 
> fecc3cf introduces the desired behaviour.
> 
> 6a2b890 broke the suppression of footnote-reference in the summary by adding an id parameter to the \<sup\> elements for back-reference.
> 
> Fixes #2961.
> 
> Ref: https://zola.discourse.group/t/drop-footnote-references-from-summary-if-bottom-footnotes-true/2841/2

TL;DR: the regular expression that was locating `footnote-references` for deletion in `summary`wasn’t up to date with the introduction of an `id` attribute, for back-references.
