  crbug.com/559557312: when a fractional advance makes the shaped width of a

  fitting break opportunity land 1/64px above the available width,

  BreakText() reports an overflow but keeps a ShapeResult, and the

  HandleOverflow() retry caps the available width at the shaped width minus

  1px. If that returns no result, the stale shape remains attached to an

  extended text range.

  letter-spacing provides a fractional advance that does not depend on

  subpixel positioning, which web tests disable on some platforms. The last

  div is the reviewer-provided zoom-based variant for environments where

  subpixel positioning applies.
