Wrong build directory passed to qmlls

When using the QML language server then we pass the Qt installation directory as "build directory" to qmlls.

This is how the process is started for a simple QtQuick project:

"D:\Qt\6.7.0\msvc2019_64\bin\qmlls.exe" -b "D:\Qt\6.7.0\msvc2019_64"

current directory: D:\TEMP\QtQuickApplication1

For reference: https://doc-snapshots.qt.io/qt6-dev/qtqml-tooling-qmlls.html#setting-up-the-qml-language-server-in-your-editor

Please clarify with the qmlls guys, but I'm pretty sure the way we're doing it right now is incorrect.
