as discussed here: https://forum.camunda.org/t/hidecompletebutton-being-reset-in-recent-camunda-versions/16302, the hideCompleteButton function does not function 100% of the time.  Example, if you set hideCompleteButton = true, and then claim a task, the complete button will appear.  if you then click into another task and then return to the original task, the complete button will be hidden.

When

• I deploy and start the attached process
• I claim the task

Then

• The Complete buttons appear again

Expected

• The control buttons stay hidden

Note
When selecting another task and coming back, the buttons are hidden again
