div {
  border: 5px solid;
  width: 2em;
}

div:nth-of-type(1) { border-color: blue; }
div:nth-of-type(2) { border-color: green; }
div:nth-of-type(3) { border-color: orange; }

div:nth-of-type(3) { word-break: break-all; }
</style>

<p>Test passes if the text in each of the following 3 boxes is broken into separate lines at the same points.
<div lang=ja>あい)あ(い</div>
<div lang=ja>あ<br>い)<br>あ<br>(い</div>
<div lang=ja>あい)あ(い</div>

<!--
If the first box (blue) is wrong,
customary rules for line breaking japanese are not implemented (or not correctly).

If the third box (orange) is wrong,
customary rules for line breaking japanese are discarded
when applying 'word-break: break-all', which is a spec violation.
