Setting the `Module['websocket']` at runtime does not work since version 3.1.71

Since version 3.1.71, setting the `Module['websocket']` at runtime does not work anymore.

I tried setting `Module['websocket']` using `emscripten_run_script` and `EM_JS`.

I think it could be linked to https://github.com/emscripten-core/emscripten/pull/22774.

**Version of emscripten/emsdk:**

```
emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 3.1.72 (437140d149d9c977ffc8b09dbaf9b0f5a02db190)
clang version 20.0.0git (https:/github.com/llvm/llvm-project 1c4caece05f1885ba6ed80755d6b5de1b9f99579)
Target: wasm32-unknown-emscripten
Thread model: posix
InstalledDir: /emsdk/upstream/bin
```

**Build command:**

```
emcc test.cpp -o index.html -sEXPORTED_FUNCTIONS=_main -sSOCKET_DEBUG=1
```

**Source test.cpp:**

```cpp
#include
#include
#include
#include
#include
#include
#include

int main() {
emscripten_run_script("Module['websocket'] = {url: 'wss://MY_URL', subprotocol: 'binary'}");

int _fd = ::socket(PF_INET, SOCK_STREAM, IPPROTO_TCP);
sockaddr_in server;
memset(&server, 0, sizeof(server));
server.sin_addr.s_addr = inet_addr("172.29.1.0");
server.sin_family = AF_INET;
server.sin_port = htons(443);

auto res = ::connect(_fd, (struct sockaddr*)&server , sizeof(server));
std::cout << "!! " << res << " " << errno << std::endl;

return 0;
}
```

**Result with 3.1.72:**

```
websocket: connect: ws://172.29.1.0:443/, binary
!! -1 23
```

**Result with 3.1.72, using the `emcc` option `-sWEBSOCKET_URL=wss://MY_URL`:**

```
websocket: connect: wss://MY_URL, binary
websocket: adding peer: 172.29.1.0:443
!! 0 0
```

**Result with 3.1.70:**

```
websocket: connect: wss://MY_URL, binary
websocket: adding peer: 172.29.1.0:443
!! 0 0
```
