/* The line thumbnail had a sized 64x64 BOX but nothing sizing the <img> inside
   it. An img with no width/height and no loaded source measures 0x0, and the
   browser will not fetch a lazily-loaded element that occupies no space — so
   the asset returned 200 when requested by hand and was never requested by the
   page. Sizing the img (and the <picture> wrapper, which is display:inline by
   default and collapses the same way) is what makes the fetch happen. */
