    Temporary work arround for 1.1 to copy/paste/clone LPE flatterning on this operations
    
    Temporary work arround for 1.1 release to allow visualy OK copy/paste/clone on items with some LPE
    
    Just allow all operations visualy ok. LPE involved:
       * Slice
       * Bool
       * Mirror Symmetry in split mode
       * Rotate copyes in split mode
    
    Maybe we need to add it to more LPE.
    
    When a LPE item has external items involved, by items variable or item parameter this are not handled in our LPE
    forking system and is not trivial add it (I have a MR in a half for 1.2)
    
    This workarround the issues that cause this kind of operations on this LPE
    flattening the live effects -:(- (even if motre than one) in the copied element (retain in original)
    
    We discuss about is good and realy no but better fix need more time than we have to release 1.1
