    tdf#135001 sw_redlinehide: fix IsShown() for AT_PARA flys
    
    There is one merged text frame from node 102 to node 328 with no
    extents, and of course a shape anchored at node 271 should not be
    visible at all.
    
    This crashes because the shape was removed from the layout during
    CheckParaRedlineMerge() but then moved to the visible heaven layer
    again via sw::AddRemoveFlysAnchoredToFrameStartingAtNode() and the
    layer determines if it's visible as far as Sdr* is concerned;
    it lacks a connection to a SwFrame though.
    
    warn:legacy.osl:3547848:3547848:sw/source/core/layout/paintfrm.cxx:3861: <SwFlyFrame::IsPaint(..)> - paint of drawing object without anchor frame!?
