Array elements 'disappear' from array step after confirming desired to edit workflow

Element appear to disappear from arrays if you click the red cross button on the element before entering the workflow edit mode.

Steps to repro:

1. Open a workflow

2. Enter edit mode

3. Add an array step

4. Add an element to the array.

5. Publish the workflow

6. Click on the array step to reveal the config panel

7. Click the red cross to delete the element

8. Click ‘Confirm’ on the popup that appears asking for confirmation to edit workflow.

9. Note that the element appears to have been removed from the array.

Array elements should remain visible if red cross is clicked while not is draft mode

Actual behaviour

Array elements disappear when red cross is clicked when in draft mode
