Why in this example clickable box appears in RTL context very larger from what I have declared (2cm), in left to right context width of box is fine
% lualatex
\documentclass[12pt]{article}
\usepackage{hyperref}
\begin{document}
%\pardir TRT \textdir TRT \linedir TRT
a
{\hypersetup{pdfhighlight={/P},pdfborder={0 0 4}}%
\vbox{\hyperlink{thesentence}{\vbox to 3cm{\hbox to 2cm{ \hfil}\vfil}}}}
\newpage
Text \hypertarget{thesentence}{this sentence}
\end{document}
Result in LTR context
