Environment

• TeXstudio: 4.8.2
• Qt: 6.7.2
• OS: macOS 14.6.1
• TeX distribution: BasicTeX 2024

Expected behavior

After loading a package library, the keys defined in cwl of that library are shown in the corresponding completion list(s).

Actual behavior

Those keys are recognized (no "unrecognized key in key option" prompt), but missing in completion list(s).

How to reproduce

\documentclass{article}
\usepackage{tcolorbox}
\tcbuselibrary{breakable}

\tcbset{}

\begin{document}
\begin{tcolorbox}[]
  content
\end{tcolorbox}
\end{document}

The corresponding cwl for tcolorbox library breakable provides key breakable and many more for the option list of \tcbset, \begin{tcolorbox}, etc.

• In the argument of \tcbset{...}, type in "break" and see that there's no "breakable" in the completion list, "all" tab.
• \tcbset{break} shows "break" is unrecognized, but \tcbset{breakable} is recognized.
• In the optional argument of \begin{tcolorbox}[...], type in "break" and check the similar behavior.

Commands provided by libraries are both recognized and shown in completion list, for example \tcbbreak in breakable library.

It seems to me this is a regression, though I'm not sure.
