title: PHPMyAdmin Designer does not show relations
body: <p>When using the PHPMyAdmin Designer tool I can not see relations (lines that connect each foreign key relation). The foreign key attributes get a different icon than the other attributes, however the line connection is missing. I already tried switching on/off "Show/Hide relations". <img src="https://i.stack.imgur.com/42UGe.png" alt="PHPMyAdmin Designer"></p>
  
  <p>What am I missing?</p>
