Destaque realisticamente o título e a numeração do teorema

Recentemente eu descobri issopostagem incrível sobre destaque de texto legal em LaTeXe a resposta correspondente de @Antal Spector-Zabusky. Eu quero implementar esse destaque em minhas notas de aula. Em particular, tenho vários ambientes definidos (como definição, observação e proposição) (usando mdframede amsthm).

Aqui está um exemplo mínimo

\documentclass{report}

\usepackage{amsthm}
\usepackage{xcolor}
\usepackage{mdframed}

\definecolor{superlight}{HTML}{F5F5F5}
\mdfdefinestyle{basic-gray-box}{backgroundcolor=superlight}

\setlength{\parindent}{0pt}

\newtheoremstyle{mystyle}
  {}
  {}
  {\itshape}
  {}
  {\bfseries}
  {.}
  { }
  {\thmname{\highlight{#1}}\thmnumber{ #2}\thmnote{ (#3)}}%  

\theoremstyle{mystyle}
\newmdtheoremenv[style=basic-gray-box]{proposition}{Satz}[chapter]

% Highlight
\usepackage{soul}
\usepackage{tikz}
\usetikzlibrary{calc}
\usetikzlibrary{decorations.pathmorphing}

\makeatletter

\newcommand{\defhighlighter}[3][]{%
  \tikzset{every highlighter/.style={color=#2, fill opacity=#3, #1}}%
}

\defhighlighter{yellow}{.5}

\newcommand{\highlight@DoHighlight}{
  \fill [ decoration = {random steps, amplitude=2pt, segment length=15pt}
        , outer sep = -30pt, inner sep = 0pt, decorate
        , every highlighter, this highlighter ]
        ($(begin highlight)+(0,8pt)$) rectangle ($(end highlight)+(0,-3pt)$) ;
}

\newcommand{\highlight@BeginHighlight}{
  \coordinate (begin highlight) at (0,0) ;
}

\newcommand{\highlight@EndHighlight}{
  \coordinate (end highlight) at (0,0) ;

\begin{document}

\chapter{}

What the highlighting looks like:
\begin{proposition}\end{proposition}

What I want it to look like: \\
\textbf{\highlight{Satz 1.1. (my title)}}

\end{document}

Isso produz um documento como este:

Em particular, observe que a "aleatoriedade" no destaque é removida (é apenas uma caixa transparente ao redor de "Satz"). Também quero que o destaque ocupe todo o título (Satz, numeração, nome).

Como posso abordar isso?

Este é um problema de expansão. Você precisa expandir o argumento \highlightprimeiro. Aqui está uma maneira de fazer isso. Ele define uma variante, \Highlightque expande o argumento primeiro. (É claro que existem outras maneiras, por exemplo, usando \expandafter.)
