    itemize: Don't change font for line separator
    
    If we render this (in single-paragraph mode), we
    draw a hex box, so changing font just for the line
    separator is never useful, and in fact, counterproductive
    in cases where the font has a (typically empty) glyph
    for it.
    
    This fixes the [LS] or [PS] hex boxes not showing up
    in single-paragraph mode depending on font fallback.
