Package Footnote and Biblatex: only fullcites in table

Question

I have a question about citation in tables/tabulars.

I use biblatex with style verbose-ibid and the package footnote to get the cites working in tables/tabulars: Here I use \savenotes and \spewnotes to retrieve the cites from my table. The problem is, I obviously don't get the wanted \autocite but some other citation-style, always something that would be the \fullcite from biblatex.

Look at my MWE: After a shorthand is introduced, it should also be used by \autocite! But in my tables I always get a fullcite. Also my text-cite 7 should know the shorthand, which is introduced in the table, but it doesn't.

Any ideas to get the footnote-package working with biblatex?

\RequirePackage{filecontents}
\begin{filecontents*}{bibl.bib}
@BOOK{something,
title={{Fulltitle with many many characters}},
shorthand={SHORTHAND},
address = {City},
publisher = {Publ},
year = {1961},
language = {{Latin}},
}
@BOOK{another,
title={{Another Fulltitle with many many characters}},
shorthand={ANOTHERSHORTHAND},
address = {City},
publisher = {Publ},
year = {1963},
language = {{Latin}},
}
\end{filecontents*}


\documentclass{article}


\usepackage{caption}
\usepackage{placeins}
\usepackage{footnote}

\usepackage[
style=verbose-ibid,
backend=biber,
bibwarn=true,
]{biblatex}

\addbibresource{bibl.bib}

\begin{document}


bla\autocite[1]{something}
bla\autocite[2]{something}

%table
\newcommand{\tabcolA}{p{\dimexpr 0.33\linewidth-2\tabcolsep}}

\savenotes
\begin{table}[ht]
\begin{tabular}{|\tabcolA | \tabcolA | \tabcolA |}
\hline
  header & header & header \\
  \hline
  some text with footnote\autocite[3]{something} & sometext & some text with footnote\autocite[4]{something} \\
  some text with footnote\autocite[5]{another} & sometext & some text with footnote\autocite[6]{another} \\
\hline
\end{tabular}
\caption{Differences in some texts}
  \label{tab:mytextdiff}
\end{table}
\FloatBarrier
\spewnotes

bla\autocite[7]{another}. bla\autocite[8]{something}

\end{document}

Thanks to moewe and this nice codesnippet here, I could put together a working code: With a bit manual work (see code below) now footnotes in tables should act like biblatex-footnotes and work together with the hyperref-package. (The footnote-package couldn't help.)

\RequirePackage{filecontents}
\begin{filecontents*}{bibl.bib}
@BOOK{something,
title={{Fulltitle with many many characters}},
shorthand={SHORTHAND},
address = {City},
publisher = {Publ},
year = {1961},
language = {{Latin}},
}
@BOOK{another,
title={{Another Fulltitle with many many characters}},
shorthand={ANOTHERSHORTHAND},
address = {City},
publisher = {Publ},
year = {1963},
language = {{Latin}},
}
\end{filecontents*}
