Description
I'm experiencing problems with created QOffscreenSurface objects being invalid when building my Qt application for WASM.
How to reproduce
The problem can be reproduced by adding assert(m_offscreenSurface->isValid()) checks to the quick/rendercontrol sample project as shown in https://codereview.qt-project.org/c/qt/qtdeclarative/+/296531. The following assertion then fail when running in debug mode:
Application exit (RuntimeError: abort(Assertion failed: m_offscreenSurface->isValid(), at: ../source/window_singlethreaded.cpp,117,WindowSingleThreaded).
