Adds explanation about why not sending super in the recent selectionIndex: fix.
=============== Diff against Morphic-ct.1772 ===============
Item was changed:
----- Method: PluggableMultiColumnListMorph>>selectionIndex: (in category 'selection') -----
selectionIndex: viewIndex
listMorphs do: [:listMorph | listMorph selectedRow: (viewIndex min: self listSize)].
+ "ct: As per the invariant defined in #setListParameters, listMorphs always includes listMorph. Subsequently, every super send in #selectionIndex: would be without effect because #selectionIndex already has been updated in the child class. Since selection highlighting is also not relevant for multi-column list morphs (this hook is only used by SimpleHierarchicalListMorph), we can refuse this bequest but send #scrollSelectionIntoView manually."
self scrollSelectionIntoView.!
