Steps to reproduce:

1. open advanced demo
2. replace tasks with:

   gantt.taskStore.data = [
   {
       "startDate": "2019-01-14",
       "endDate": "2019-01-15",
       "name: : "task 1",
       "duration": 1
   },
   {
       "startDate": "2019-01-14",
       "endDate": "2019-01-15",
       "name: : "task 2",
       "duration": 1
   },
   {
       "startDate": "2019-01-14",
       "endDate": "2019-01-15",
       "duration": 1,
       "name: : "task 3",
       "expanded": true,
       "children": [
           {
               "startDate": "2019-01-14",
               "endDate": "2019-01-15",
               "name: : "task 3-1",
               "duration": 1
           }
       ]
   }
   ]

3. start cell editing "task 1"

Result: "Predecessors" column editor dropdown list has no "task 3-1" entry
