* Although widely used for that purpose, hyperlinks are disliked for footnote linking.
* Browsers may need to be prevented from logging these clicks in the browsing history,
* as logging compromises the usability of the 'return to previous' button in browsers.
* For that purpose, and for scroll animation, this linking is performed by JavaScript.
*
* Link elements raise concerns, so that mitigating their proliferation may be desired.
*
* By contrast, due to an insufficiency in the CSS standard, coloring elements with the
* theme’s link color requires real link elements and cannot be done with named colors,
* as CSS does not support 'color: link|hover|active|visited', after the pseudo-classes
* of the link element.
*
* Yet styling these elements with the link color is not universally preferred, so that
* the very presence of these link elements may need to be avoided.

* This assignment was overridden by another one, causing the algorithm to jump back
* near the post start to a position calculated as the sum of the length of the last
* footnote and the length of the last footnote replace text.
* A bug disturbing the order of the footnotes depending on the text before the first
* footnote, the length of the first footnote and the length of the templates for the
* footnote and the tooltip. Moreover, it was causing non-trivial process garbage.
