I have more information to share. It seems that whenever I add the tag `{% favicon %}` in my header, each and every page that ends up being generated into an index.html provokes the generation of the favicons.
Is it really so that this plugin generates the favicon for each index.html?

**Important note:** If the source file for the favicon is a `PNG`instead of an `SVG`, the issue doesn't happen.
