[FG-TUM]

Type of JetBrains IDE (IntelliJ, PyCharm, etc.) and version

Dataspell

Operating System

Linux / Windows

TeXiFy IDEA version

What I did (steps to reproduce)

Text in [ ], e.g., in a description environment, seems to be excluded from spell checks.

Minimal example to reproduce the problem

\documentclass{article}
\begin{document}
  \begin{description}
    \item[Tpyo]
    Tpyo
  \end{description}
\end{document}

Expected behavior

Warning about a misspelled word in lines 4 AND 5.
The expected Message for the word in [ ] would be: Typo in word 'Tpyo'.

Actual behavior

No Warning about a misspelled word in line 4, only in 5.
