<meta name="assert" content="trailing pre-wrap spaces hang conditionally before forced breaks, which is different from not hanging at all, as it doesn't cause wrapping at earlier opportunities.">

<style>
div {
  font-size: 2rem;
  font-family: Ahem;
  width: 3ch;
}
#test {
  white-space: pre-wrap;
  color: green;
}

.ref {
  white-space: pre;
  color: red;
  position: absolute;
  z-index: -1;
}

</style>

<p>Test passes if there are green rectangles below and no red.
