title: Primefaces tieredMenu, Chrome only bug - The subitems disconnects from the menu
body: <p>The sub items overlay panel disconnects from the main menu with a small gap and when try to hover it closes making impossible to select an item.
  It is not reproducible always. We found it while increasing and decreasing screen resolution. I can't say it happens in a specific resolution.</p>
  
  <p>Primefaces 6.2
  Chrome version: 79.0.3945.130</p>
  
  <pre><code>    &lt;p:commandButton value="Manage Menu" id="managePrjMenu"/&gt;   
          &lt;p:tieredMenu overlay="true" trigger="managePrjMenu" my="left top" 
                        at="left bottom" style="width:auto;&gt;
               &lt;p:submenu label="SubMenu1"&gt;
                  &lt;p:menuitem url="url1" value="subMenuItem1"/&gt;
               &lt;/p:submenu&gt;
               &lt;p:menuitem url="url2" value="menuItem1"/&gt;
