Syntax Highlight Problem for Latex/Tikz

Question

I have a tikzpicture inside a latex file. My problem is that when I open the file and jump with GG to the end of the file, the math environment inside the tikz-nodes is not highlighted (e.g. $v_0^1$). The dollar signs as well as the stuff inside it is 'white'. However, when I scroll (pressing j) from the start to the bottom, it highlights the math stuff correctly (dollar signs as well as the math content). I have no clue why this happens.

I tried to create a minimal working example, and I really need the spaced lines + singleton lines to have the bug, otherwise it works correctly. Some things which might be interesstring to know: Removing the \section-command does fix the problem. My file has 144 lines, When I press GG, the topmost line I still see is line 113. I run Arch Linux and vim version 'version 8.2.1704'. My .vimrc is

syntax enable
let g:tex_flavor = 'latex'

The file:

\documentclass[a4paper,11pt]{book}
\begin{document}
w






























\section{test}
test

      \begin{tikzpicture}
        \node[ above left = 8ex and 8ex of v1] (v01) {$v_0^1$};
        \node[ below left = 8ex and 8ex of v1] (v02) {$v_0^\PVCParal$};
        \node[below left = 1ex and 2ex of v02] (labelV0) {\Large$V_0(\GK)$};
      \end{tikzpicture}

While I can't suggest why this happens (cf. :help :syn-sync), a usual fix is :syntax sync fromstart, or to increase maxlines, or similar tweaks.
