<!--
 | Wrapping is only performed at an allowed break point, called a soft wrap
 | opportunity. In most writing systems, in the absence of hyphenation a soft
 | wrap opportunity occurs only at word boundaries.
 |   https://www.w3.org/TR/css3-text/#soft-wrap-opportunity
 |
 | Wrapping cannot occur before the line is justified. Inline elements with
 | non-zero margins, padding, and borders in a box justify the line.
 | https://www.w3.org/TR/CSS21/visuren.html#phantom-line-box
 |
 | While the spec is not clear as to whether the start or end edge of an
 | inline element with non-zero margins, padding, and borders justifies the
 | line, both WebKit and Firefox treat the end edge as the point where
 | justification occurs; resultantly, Cobalt also treats the end edge as the
 | point of justification.
