title: Chrome devtools network tab - websocket message source/initiator
body: <p>I have a websocket that sends some messages to my server and I would like to find out what code is causing the messages to be send.<br />
  I can see the websocket and its messages by opening the chrome devtools, going to the network tab, looking for the request of type <code>websocket</code>, clicking on it and going to the tab <code>messages</code>. When looking at the requests in the network tab itself, they have a column <code>Initiator</code>, which links to the code having initialized the request, the same sadly isn't true for the messages overview.</p>
  <p>How can I get the same information for each individual message?</p>
