UndoManager.item should probably return a sequence, not an IDL array object from Boris Zbarsky on 2012-09-20 (public-webapps@w3.org from July to September 2012)

Given that .item() returns a new object every time, I don't see the use 
cases for returning an IDL array object.  On the other hand, there are 
drawbacks (e.g. it's not an actual JS array, unlike sequence).  Are 
there any particular reasons this is returning an IDL array object?

If there _are_, then at the very least the spec needs to define what 
sort of IDL array object this is.  There are three different kinds...
