Menu UI is missing with micon_menu enabled

Problem/Motivation

Menu UI is missing with micon_menu enabled. It's entirely missing.

I think it happens around here:

/**
 * Implements hook_module_implements_alter().
 */
function micon_menu_module_implements_alter(&$implementations, $hook) {
  if ($hook == 'form_node_form_alter') {
    unset($implementations['menu_ui']);
    // Move micon_menu_form_node_form_alter() to the end of the list.
    $group = $implementations['micon_menu'];
    unset($implementations['micon_menu']);
    $implementations['micon_menu'] = $group;
  }
}
