Steps to Reproduce:

1. Go to Control Panel > Configuration > Workflow
2. Edit the existing Single Approver definition
3. Scroll down to the <assignments> tag on the editor

Expected Result:
The definition is formatted nicely with line breaks.

Actual Result:
Remaining code is all formatted on 1 line. It is difficult for the reader to read and it the code.

This also affects any uploaded definitions.

Reproduced on:
Master: ab3ebb3c9d583fe02a0211156ab1c902a1754268

Does not apply 7.0 because the definition cannot be edited in the UI and the Source definition editor in Kaleo Designer does not have this issue.
