Resalte de manera realista el título y la numeración del teorema.

Recientemente me encontré con estopublicación increíble sobre resaltado de texto interesante en LaTeXy la respuesta correspondiente de @Antal Spector-Zabusky. Quiero implementar este resaltado en mis apuntes de clase. En particular, tengo múltiples entornos definidos (como definición, comentario y proposición) (usando mdframedy amsthm).

Aquí hay un ejemplo mínimo.

\usepackage{xcolor}
\usepackage{mdframed}

\definecolor{superlight}{HTML}{F5F5F5}

\setlength{\parindent}{0pt}

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

\theoremstyle{mystyle}

% Highlight

\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) ;

\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}

Esto produce un documento como este:

En particular, tenga en cuenta que se elimina la "aleatoriedad" en el resaltado (es solo un cuadro transparente alrededor de "Satz"). También quiero que el resaltado abarque todo el título (Satz, numeración, nombre).

¿Cómo puedo abordar esto?

Respuesta1

Este es un problema de expansión. Es necesario ampliar el argumento del \highlightprimero. Aquí tienes una forma de hacerlo. Define una variante, \Highlightque expande el argumento primero. (Por supuesto, hay otras formas, por ejemplo, usando \expandafter).
