+    - message: >-
+        Restrict override of margin-bottom for fitem_id_answer_* and
+        fitem_id_fraction_* divs to own edit form. Question type
+        plugins currently benefitting from the unlimited style override
+        will need to change their styles.css accordingly. An example
+        can be found in calculatedmulti's style sheet.
