如何解决 Safari 10.1 错误 "Failed to send WebSocket frame"？

Question

Safari 10.1 中的 WebSocket API 似乎有最大数量的二进制数据可以缓冲，然后发送的下一条消息出现错误 "WebSocket connection to ... failed: Failed to send WebSocket frame."

Safari 然后关闭与代码 1006 (CLOSE_ABNORMAL) 的连接。

WebSockets 是 supposed to report the bufferedAmount - 但 Safari 总是报告 0 直到错误发生后连接关闭。

我尝试在每条消息之间设置 100 毫秒的 setTimeout，这似乎适用于小块数据的情况，但它似乎很脆弱，大块在我发送结束时仍然会出错 JSON消息，即使有更长的延迟。

你可以see the bug in action here - the "Play Sample" buttons work in Safari 10.03 but error in 10.1. (Code that handles the WebSocket connection.)

关于如何解决这个问题有什么想法吗？或者限制甚至是多少？我知道 Safari 是开源的，但我不确定去哪里找。

更新：这是一个更简单的例子：

// this fails in Safari 10.1 but works in 10.03 (and other browsers)
var ws = new WebSocket('wss://echo.websocket.org');

ws.onerror = function(evt) {
  // Not sure why, but error events seem to have no useful information
  // The console, however, will have the following error:
  // WebSocket connection to 'wss://echo.websocket.org/' failed: Failed to send WebSocket frame.
  console.log("WebSocket error - see console for message");
}
ws.onclose = function(evt) {
  console.log(`WebSocket closed with code: ${evt.code}, reason: ${evt.reason}`);
}

ws.onopen = function() {
  console.log('sending first binary message');
  ws.send(new Uint8Array(23085));
  console.log('bufferedAmount is ' + ws.bufferedAmount);

  // this gets the error
  console.log('sending second binary message');
  ws.send(new Uint8Array(23085));
  console.log('bufferedAmount is ' + ws.bufferedAmount);

  console.log('sending third binary message');
  ws.send(new Uint8Array(23085));
  console.log('bufferedAmount is ' + ws.bufferedAmount);

  ws.close();
}

第二条消息获取错误关闭连接，第三条消息后，bufferedAmount为23093。
