If UILabel iOS auto shrink is not working

There is an issue I've got today, UILabel has not not autoshrinking text to fit label size. Investigation gives the answer - do not select "Word Wrap" in Line Breaks parameter for this label control, select "Truncate Tail" (see illustration) and it magically starts to work.
