The error in pictures

The code snippet below illustrates the problem. Any occurrence of \{ inside a string causes a false coloring in the block between curly brackets following it.

   /**

     * Otherwise, $noSortArray is from admin::configure::updateNoSort()
     *
     * @param array $noSortArray Default is []
