[wasm] Signal from another thread is discarded while the thread is temporarily blocking

Details

    • WebAssembly

    Description

      Sending a signal to a QObject that lives on a different thread and while it is temporarily blocking, causes the signal to be discarded.

      The same seems to work on Qt 6.4.2 when Qt is built for wasm multi-threaded

      To reproduce the issue please run the attached example with Qt for wasm multi-threaded.

      1. Observe the slot doSomething() in class Service is not invoked.
