title: Unexpected console messages when initializing a WKWebView
body: <p>Whenever I create a WKWebView object, I've suddenly started getting a series of messages in the console that I've never seen in the past:</p>
  <pre><code>WF: === Starting WebFilter logging for process MyApp
  WF: _userSettingsForUser : (null)
  WF: _WebFilterIsActive returning: NO
  </code></pre>
  <p>This happens even if I just initialize the object without doing anything with it, and setting a breakpoint immediately after it suggests the messages are being generated during the init method:</p>
  <pre><code>_ = WKWebView(frame: UIScreen.main.bounds)
  /* breakpoint here, messages are already in the console */
  </code></pre>
  <p>When I search for the messages on Google, everything that comes up seems to be related to Admob which I'm not using or other specific cases that don't apply, and most of them are from several years ago but I haven't seen this before today.</p>
  <p>What do these messages mean? Can I get rid of them? Note that disabling <code>OS_ACTIVITY_MODE</code> is not an option, I don't want to just hide everything.</p>
  <p>After further testing, this seems to only happen in iOS 13.4 or later, but I can't find any release notes or anything about it so I'm not sure whether it's a bug or part of a new feature. I still want to be able to get rid of it either way though.</p>
