<meta name=assert content="breaks before U+2010 or U+2013 when line-break is strict are not allowed when the preceding character has class ID.">
<style>
div {
  width: 2em;
  line-break: strict;
  border: solid cyan;
}
</style>

<p>The test passes if the second line in each box below ends with a hyphen.
(Note: the hyphens in each box do no need to be the same size.)
