qmlls can find a module but not its types

The attached project has this structure:

.
├── CMakeLists.txt
├── MyApp
│   ├── CMakeLists.txt
│   ├── Main.qml
│   ├── main.cpp
└── MyLib
    ├── CMakeLists.txt
    └── GreenRect.qml

Additionally, it uses:

• set(QT_QML_GENERATE_QMLLS_INI ON)
• qt_standard_project_setup(REQUIRES 6.8)
• qt_add_qml_module(appMyApp IMPORTS TARGET MyLib ...)

The attached project contains my .qmlls.ini files for inspection.

Steps to reproduce

1. Ensure that qmlls is enabled
2. Build and run the attached project, including the "all_qmllint" target
3. Quit and then re-launch Qt Creator
4. Load the same project and open Main.qml in the editor

Outcomes

• (Step #2) qmllint reports no problems (Expected)
• (Step #2) The project runs fine (Expected)
• (Step #4) qmlls can find the module from "import MyLib" (Expected)
• (Step #4) qmlls cannot find the GreenRect type; restarting qmlls does not change anything (Not Expected)
