Biblatex sidenote issue with Tufte-Book Class

Question

I followed the solution to the best of my ability as found in this link: Can I use biblatex with Tufte classes?

However, I am still having an issue with getting the side notes to properly show up in the margin. Here is my MWE:

\RequirePackage[l2tabu, orthodox]{nag}
\RequirePackage[hyphens]{url}
\documentclass[a4paper,twoside,nobib]{tufte-book}
\hypersetup{colorlinks, citecolor=blue}
\usepackage{hyphenat}
\usepackage{xpatch}
\usepackage[T5,T1]{fontenc}
\usepackage[english]{babel}
\usepackage[autostyle=true]{csquotes}
\usepackage[
style=verbose,
autocite=footnote,
sorting=nty,
citecounter=true,
citetracker=true,
backref=true,
backend=biber
]{biblatex}
\addbibresource{HSFSS-BIBLATEX.bib}
\newcommand{\openepigraph}[2]{%
  \begin{fullwidth}
  \sffamily\small
  \begin{doublespace}
  \noindent\allcaps{#1}\\% epigraph
  \noindent\allcaps{#2}% author
  \end{doublespace}
  \end{fullwidth}
}%
\begin{document}
\openepigraph{
Is England and nowhere. Never and always.
}{—T.S. Eliot\autocite{TSEliot}
}
\vfill
\openepigraph{
The Sky is blue.
}{—Author\autocite{Tufte2001}}
\printbibliography
\end{document}

Here is my .bib file:

@MISC{tseliot,
    author = {Eltiot, T. S.},
    title = {\textit{Four Quartets}{ | Quartet No. 4: Little Gidding}},
    date = {},
    note = {December 2013 [Accessed 27 January 2022]},
    howpublished = {\url{http://davidgorman.com/4quartets/4-gidding.htm}}
}

@BOOK{Tufte2001,
    author = {Edward R. Tufte},
    title = {The Visual Display of Quantitative Information},
    publisher = {Graphics Press},
    year = {2001},
    address = {Cheshire, Connecticut},
    isbn = {0-9613921-4-2}
}

Answer 1

With a modified definition of \openepigraph

\openepigraph{<epigraph>}{<author>}{\autocite{<to author work>}}

% !TeX TS-program = pdflatex

\RequirePackage[l2tabu, orthodox]{nag}
