title: Allow Flash content in Chrome 69 running via chromedriver
body: <p>Does anybody know how to enable Flash plugin in Chrome 69.
  I use chromedriver 2.41 with java selenium bindings.
  I've tried with </p>
  
  <pre><code>prefs.put("profile.default_content_setting_values.plugins", 1);
  prefs.put("profile.content_settings.plugin_whitelist.adobe-flash-player", 1);
  prefs.put("profile.content_settings.exceptions.plugins.*,*.per_resource.adobe-flash-player", 1);
  </code></pre>
  
  <p>but with no luck.
  I've also tried to compare chrome profile preferences with disallowed/allowed flash for particular site and then tried with:</p>
  
  <pre><code>            Map&lt;String, Object&gt; site = new HashMap&lt;&gt;();
              Map&lt;String, Object&gt; values = new HashMap&lt;&gt;();
              Map&lt;String, Object&gt; setting = new HashMap&lt;&gt;();
              setting.put("flashPreviouslyChanged", true);
              values.put("last_modified", "13180613213099316");
              values.put("setting", setting);
              site.put("http://my.site,*", values);
              prefs.put("profile.content_settings.exceptions.flash_data", site);
  </code></pre>
  
  <p>but it won't work as well.</p>
  
  <p>I've also tried to run with profile specified via</p>
  
  <pre><code>options.addArguments("user-data-dir=" + profileDir);
  </code></pre>
  
  <p>but since this white list setting becomes 'ephemeral' in Chrome 69 it also won't work.</p>
  
  <p>Is there any method to run my automation in Chrome with flash support?</p>
