  After an upgrade to Joomla 3.8.13 and Civi 5.6.0 the Joomla admin menu dropdown is stacking under the Civi menu. I can't reproduce on <https://joomla.demo.civicrm.org> as even if the versions weren't 3812 and 560, the Joomla admin menu isn't long enough.

  I can confirm that restoring the z-index that was removed in root/administrator/components/com_civicrm/civicrm/css/joomla.css corrects this issue. The rest of the removed code makes no difference. This works for me:
  ul#civicrm-menu {
  z-index: 1;
  position: relative;}

  There was a [commit](https://github.com/civicrm/civicrm-core/commit/8aa67b8570e786f5d0348d2d1bedeeebca17fafb) that fixed css for shoreditch theme probably that might have caused the regression in Joomla. Can you try to replace the code from the [commit](https://github.com/civicrm/civicrm-core/commit/8aa67b8570e786f5d0348d2d1bedeeebca17fafb) and see if it works? If so I can file a issue and submit the patch for regression.
