The second text block has been optimized for screen readers (see the 24-second video comparison):

  1. an opacity: 0 full stop has been inserted after the “Location” heading via the CSS ::after pseudo-element,
  2. a zero-width space (​) has been inserted between “SF” and “JAZZ” and the latter appears in the source code as “Jazz” and is then upper-cased via CSS text-transform: uppercase.

These two optimizations have originally appeared in Chrome’s Developer Diary #Day8 video.
