Highlighting regular expression %TODO does not work correctly

[betz-michael]

Environment

• TeXstudio: 4.7.0
• Qt: 6.6.1
• OS: Windows 10)
• TeX distribution: miktex

Expected behavior

With Version 4.6.3 every character after the %TODO key got highlighted for the whole document.

Actual behavior

With Version 4.7.0 just the %TODO key before the \begin{document} command are highlighted.
Commenting out %\begin{document}, saving the file, opening it again, leads to all %TODO keys being highlighted.
The same behaviour occurs with other environment like \begin{figure}. %TODO keys in those environments are not highlighted after opening a .tex file.

Newly added %TODO keys are highlighted in all cases.
Therefore the issue is connected to opening a file.

How to reproduce

Open a .tex-file which contains %TODO keys before and after the \begin{document} or in another environment command.

not reproducible.
please provide a complete example with files and screenshot.

apparently it needs to be a single file document.
