Help for \HyperRaiseLinkHook needed

So far I was able to raise the hook of internal links for better hover preview as offered by TeXShop, for example.
For unknown reasons, this doesn't seem to work anymore.
I seem to be using hyperref 2026-04-24 v7.01q.
Here is a small example file:

\documentclass{article}
\usepackage{amsmath}
\usepackage{hyperref}

\makeatletter
\newcommand{\RaiseHook}[1]{\renewcommand\HyperRaiseLinkHook%
{\setlength\HyperRaiseLinkLength{#1\baselineskip}%
\global\let\HyperRaiseLinkHook\@empty}\ignorespaces}
\makeatother

\begin{document}
\noindent
Vandermonde's determinant:
\RaiseHook{3.2}  %Supposed to make the matrix fully visible when clicking on the link below
\begin{equation}\label{VandemondeDet}
\det\begin{pmatrix}
1&x_1&x_1^2&\ldots&x_1^{d-1}\\
1&x_2&x_2^2&\ldots&x_2^{d-1}\\
1&x_3&x_3^2&\ldots&x_3^{d-1}\\[-1\jot]
\vdots&\vdots&\vdots&\ddots&\vdots\\
1&x_d&x_d^2&\ldots&x_d^{d-1}\\
\end{pmatrix}
\end{equation}
To calculate the determinant (\ref{VandemondeDet}), we proceed by induction $\ldots$
\end{document}

Any suggestions how to get back the old behaviour?
Thanks a lot in advance!

Start with the supplied minimal LaTeX example and inspect hyperref's handling of \HyperRaiseLinkHook in v7.01q. Reproduce the link to VandemondeDet and compare the PDF target area with the expected raised-hook behavior; done when the matrix is fully visible again or the changed behavior is explained.
