I am writing a thesis and added some old code to achieve a citation style, in which a short citation is placed at the bottom of the page together with additional footnotes. This requires the manyfoot package and the code given below is based on the following questions:
Biblatex cite with footnote only once, with use of brackets and Biblatex footcite: customizing biblatex and bibliography style and How to cut out a prefix in the doi field if present
I am using the newpxtext package and want a slighlty increased line spacing for the whole document (including captions, footnotes, etc.) and a more pronounced line spacing for the text. If I understood it correctly, this should be achieved by
\linespread{1.05}
\usepackage{setspace}
\setstretch{1.3}
Unfortunately, the setstretch setting leads to an undesired spacing within the footnotes, but only between lines of a single footnote (!) and not between two different footnotes (see pictures). This is in contrast to what I read in several questions (for instance Double line spacing and Set 1,5 line spacing in footnotes). If I exclude the setstretch command, the vertical spacing within the footnotes looks uniform and correct.
How do I get rid of this additional spacing within longer footnotes (for both FootnoteA and FootnoteB) and achieve the desired spacing?
MWE (for the first picture without \setstretch{1.3}; second picture with \setstretch{1.3}):
\documentclass[fontsize=11pt,DIV=11]{scrbook}
\usepackage[USenglish]{babel}
\frenchspacing
\usepackage{newpxtext}
\usepackage{newpxmath}
\linespread{1.05}
\usepackage{setspace}
%\setstretch{1.3}
\usepackage{xcolor}
\usepackage{manyfoot}
