docs: def _fix_overlapping_graphics( spansStartingFrom ):
      ''' Provides a fix for overlapping annotations that are formatted graphically
          (underlined or printed in non-default color).
          
          If two graphically formatted annotations overlap, and if one annotation,
          say A, ends within another annotation, say B, then ending of graphics of A
          also causes graphics of B to end, and so, the end of A should restart the
          the graphics of B for a continuous visualisation;
          This method modifies ending tags in a way that annotations ending within
          other annotations will also contain restarts of the corresponding (super)-
          annotations, so that a continuous formatting is ensured.
