WebSocket inside WebView?

See original GitHub issue

Is there any reason a WebSocket wouldn’t work? I get crickets, while the same code works from the main RN app.

 <WebView
        originWhitelist={['*']}
        injectedJavaScript={`

var exampleSocket = new WebSocket('ws://localhost:3000')

exampleSocket.onopen = function (event) {
  window.ReactNativeWebView.postMessage("onopen")
}

exampleSocket.onerror = (e) => {
  window.ReactNativeWebView.postMessage('onerror')
}

exampleSocket.onmessage = (e) => {
  window.ReactNativeWebView.postMessage('onmessage')
}

        `}
        source={{ html: '<html><body></body></html>' }}
      />
