'Add' button on DependencyTab no longer works via ref

Dear Bryntum Team,

We just upgraded from Bryntum Gantt 6.1.6 to 6.2.1.

Previously we used the Button ref syntax to allow us to use an items array on the Task Editor PredecessorsTab, SuccessorsTab and ResourcesTab.

the 'add' button no longer works on PredecessorsTab and SuccessorsTab. It never hits insertNewDependency() in onAddClick
the 'add' button still works on ResourcesTab.
the 'remove' button still works for all three, it still fires onRemoveClick.

sample config:

taskEdit: {
  items: {
    predecessorsTab: {
      items: {
        toolbar: {
          items: [{ ref: 'remove', text: 'Remove' }, '|', { ref: 'add', text: 'Add' }],
        },
      },
    },
  },
},
