title: Chrome does not show request cookies when "Provisional Headers are shown"
body: <p>When I set a breakpoint in my server application and make a request to the paused endpoint with Chrome, cookies are not shown in the request while the debugger is sitting on it. I spent a moment debugging why the client wasn't sending cookies until I realized what was going on - cookies exist but are not displayed. Why does this happen?</p>
  
  <p>Yes I know about <a href="https://stackoverflow.com/questions/21177387/caution-provisional-headers-are-shown-in-chrome-debugger">&quot;CAUTION: provisional headers are shown&quot; in Chrome debugger</a>, but this doesn't answer why some headers are shown and others aren't.</p>
