babel: Strange bookmarks characters in arabic pdf

[seloumi]

Brief outline of the bug

I have the following example, the headings on bookmarks when opening pdf file show strange characters unlike if we use bidi

Minimal example showing the bug

\RequirePackage{latexbug}      
\documentclass[a4paper]{book}
\usepackage{hyperref}
\usepackage[english, bidi=basic-r, layout=counters]{babel}
\babelprovide[import=ar, main]{arabic}
\babelfont{rm}{Amiri}

\begin{document}
\tableofcontents
\chapter{مقدمة}
\chapter{نظرة عامة}
\section{وجه التسمية}
\section{تاريخ}
\subsection{التيار الكهربائي}
\subsection{جدول التوزيع الإلكتروني}
\end{document}

With bidi

\RequirePackage{latexbug}      
\documentclass[a4paper]{book}
\usepackage{hyperref}
\usepackage{fontspec}
\usepackage[rldocument]{bidi}
\setmainfont[Script=Arabic]{Amiri}

\begin{document}
\tableofcontents
\chapter{مقدمة}
\chapter{نظرة عامة}
\section{وجه التسمية}
\section{تاريخ}
\subsection{التيار الكهربائي}
\subsection{جدول التوزيع الإلكتروني}
\end{document}

This is no LaTeX bug. Just load hyperref after babel with the unicode option.

\documentclass[a4paper]{book}
\usepackage[english, bidi=basic-r, layout=counters]{babel}
\usepackage[unicode]{hyperref}
\babelprovide[import=ar, main]{arabic}
\babelfont{rm}{Amiri}
