wasm: WebSockets don't actually work from other threads

    Description

      Seems that it is emscripten issue. This is set:
      https://github.com/qt/qtwebsockets/blob/v6.4.2/src/websockets/qwebsocket_wasm_p.cpp#L169

      But it is not actually implemented emscripten:
      https://github.com/emscripten-core/emscripten/blob/main/src/library_websocket.js#L304

      This probably fixes itself eventually, but this could be mentioned in documentation. Currently it can have quite poor performance when used.
