[Windows] Qt WebView produces DXGI error at startup

Steps to reproduce
Use Qt Creator to build and run the Minibrowser example: https://doc.qt.io/qt-6/qtwebview-minibrowser-example.html

Outcomes
At startup, the following message is printed to the Application Output pane many times:

DXGI ERROR: CreateDXGIFactory cannot be called from DllMain. [ MISCELLANEOUS ERROR #76: ]

Notes

• This occurs even if we set the environment variable QSG_RHI_BACKEND=opengl before creating QGuiApplication
• Unlike QTBUG-117882, my Minibrowser example still runs as expected despite these errors. Perhaps it's because I'm running an Intel GPU instead of an NVIDIA GPU
