{#
  STACK — several blocks in one cell, top to bottom (#262).

  One layout row per block, so each keeps the full width of the cell it
  sits in, in every client. The gap is padding on the row above rather than
  a margin, because the Word engine drops margins on a cell. The last row
  takes none, so the cell's own padding is all that follows the stack.

  Context: blocks — the rendered blocks, in order.
