      'For the purposes of applying the bidirectional algorithm to the paragraph-level
      container that a bdi element finds itself within, the bdi element must be treated
      like a U+FFFC OBJECT REPLACEMENT CHARACTER.'
      Thus, when a BDI contains text of the same strong direction as another BDI following it, the
      two must not form a directional run as would be the case if the BDIs were just SPANs." />
