Description

In new theme structure there is no mechanism to control footnote block top-margin & border.

Need to add in ~styles/components/specials/_footnotes.scss the following:

@page {
  @footnotes {
    margin-top: $footnote-block-margin-top;
    border-top: $footnote-block-border-top;
 }
}

and then in ~styles/variables/specials.scss the following:

// footnotes
$footnote-block-margin-top: .5em;
$footnote-block-border-top: 0;

and test.
