#43189: No latex-previews when using pgf 3.0.0 in emacs-app

     Type:  defect        |     Status:  new
 Priority:  Normal        |  Milestone:
Component:  ports         |    Version:  2.2.1
 Keywords:                |       Port:  pgf,auctex,emacs-app
--------------------------+----------------------------------
 when using auctex/latex-preview, previewing is broken when used with the
 pgf/tikz library. When previewing a document "stop-signs" appear for every
 environment which normally would be candidate for preview.

 Steps to reproduce
 1) Take a tex file which uses package tikz
 2) load it into emacs.app which has auctex and latex-preview enabled.
 3) preview the document: C-c C-p C-d


 expected: previews for the sections and other environments

 got: no previews, instead we got "stop-signs"

 example tex:
 {{{
 \documentclass{report}
 \usepackage[british]{babel}
 \usepackage{tikz}
 \begin{document}

 \begin{titlepage}
 foo
 \end{titlepage}
 \chapter{}

 \end{document}

 }}}
