* Messages enqueued with [send] are buffered in an outgoing message queue. This queue has a 16 MiB
 * limit. If a call to [send] would cause the queue to exceed this limit, the web socket will
 * initiate a graceful shutdown (close code 1001) and `send()` will return `false`. No exception is
 * thrown and no [WebSocketListener.onFailure] callback is triggered, so callers should always check
 * the return value of `send()`.
