Thread:VisualEditor/Feedback/Spurious edits to references and removal of "recommended" template

This diff (for "Tove Jansson" in the Swedish Wikipedia) illustrates a simple edit with Visual Editor gone horribly wrong. The only changes I consciously made were to correct the spelling of "Tuulikki" which was wrong in a few places. But the diff shows (1) the removal of two words and addition of a "clarify" link (line 89); (2) the removal of two references (lines 247 and 260); (3) changes within a reference (publisher, location, and ISBN) (line 279 in the new version); (4) change in a link (line 303); (5) ISBN of same (line 303); and finally (6) the removal of the "recommended" template (line 324). Several of these look like correct edits, but how did they creep in here? Several others are definitely wrong (can't make sense of the ISBN changes, for example).
