biblatex verbose-style: full citation for first occurrence of a citation on a page

Question

In biblatex's verbose style, a full citation is only printed for the first occurrence of a citation in the whole text, and afterwards always a shortened citation. I would like to have the same behaviour, but on the level of a page.

It should work in the following way: The first time a certain citation appears on a page, a full citation is printed, all subsequent citations of this source are shortened. Then on the next page, the first citation of this source is again a full citation and all subsequent citations are again short.

I found a rather old question that went into the same direction, however, I was not able to apply the answers to my problem: biblatex: is there a command analogous to \ifciteseen but within one page?

You can use the approach shown in my answer to biblatex: is there a command analogous to \ifciteseen but within one page?.

\documentclass{article}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=verbose]{biblatex}
\usepackage[colorlinks]{hyperref}
\makeatletter
\AtEveryCitekey{%
  \ifcsundef{cbx@instcount@curr@\the\c@refsection @\thefield{entrykey}}
    {\csnumgdef{cbx@instcount@curr@\the\c@refsection @\thefield{entrykey}}{0}}
    {}%
  \csnumgdef{cbx@instcount@last@\the\c@refsection @\thefield{entrykey}}{%
    \csuse{cbx@instcount@curr@\the\c@refsection @\thefield{entrykey}}}%
  \csnumgdef{cbx@instcount@curr@\the\c@refsection @\thefield{entrykey}}{\value{instcount}}}
\newcommand\iflastciteonsamepage{%
  \ifsamepage
    {\number\csuse{cbx@instcount@curr@\the\c@refsection @\thefield{entrykey}}}
    {\number\csuse{cbx@instcount@last@\the\c@refsection @\thefield{entrykey}}}}
\makeatother
\renewbibmacro*{cite}{%
  \usebibmacro{cite:citepages}%
  \iflastciteonsamepage
    {\iffieldundef{shorthand}
       {\usebibmacro{cite:short}}
       {\usebibmacro{cite:shorthand}}}
    {\usebibmacro{cite:full}}}
\addbibresource{biblatex-examples.bib}
