keyval completion fails if keys are last argument

[mbertucci47]

Environment

• TeXstudio: 4.1.2
• Qt: 6.2.1
• OS: Windows 10
• TeX distribution: miktex

Expected behavior

From this discussion it's clear that TeXstudio doesn't allow for multiple keyval completion in the same command, but it also does not allow for completion when the keys are the last argument of a non-environment command.

Actual behavior

The following cwl results in the highlighting shown:

\foo{arg}[options%keyvals]
\goo{arg1}[options%keyvals]{arg2}
\begin{env}[options%keyvals]
\end{env}

#keyvals:\foo,\goo,\begin{env}
key
#endkeyvals

The highlighting and completer work correctly for \goo (keys not the last arg) and \begin{env} (keys last arg but for an environment) but not for \foo. The \foo{arg} is essentially the same as \begin{env}, so I thought it must be a bug.

there is special treatment for environments

Is this necessary somewhere ?

The \setmainfont{font}[font features%keyvals]-type commands in fontspec and unicode-math are the main places I can think of. \pgfpagesuselayout{layout}[options%keyvals] of pgfpages is another.
