Link to Assignments missing in the Work  (Task form) popup

Description of problem:
Task form - One of the task-related popups in the Task List - does not contain link to Assignments popup (see screenshot attached)

Version-Release number of selected component (if applicable):
6.0.0.DR6

How reproducible:
Always

Steps to Reproduce:
1. Go to Tasks > Tasks List
2. Create a task using New Task
3. Click on Work icon for the new task

Actual results:
The resulting popup does not contain link to Assignment popup (unlike the other 3 popups -Task details, Task assignments and Task comments - that do contain that link).

Expected results:
The link should be present as marked in the screenshot to make the gui consistent.

Additional info:
The problem is in 
org.jbpm.console.ng.ht.client.editors.taskform.FormDisplayPopupPresenter
> method renderTaskForm, which does not add NavLink pointing to the assignment popup.
