    Resolves: tdf#103543 disable mass broadcasts from drawing objects' changes
    
    Specifically the a11y listeners are nasty bottle necks. A11y will get
    updated on paint/view. We're touching all objects on that drawing page
    to reposition so interdependencies that need to be broadcasted should
    not happen.
