<meta name="assert" content="Preserved spaces at the end of the line do not affect the intrinsic min-content size when white-space is pre-wrap. The value of overflow-wrap makes no difference.">

<style>
aside {
  float: left;
  white-space: pre-wrap;
  background: red;
}
div {
  color: transparent;
  font-family: Ahem;
  font-size: 50px;
  width: 0ch;
}
.own { overflow-wrap: normal; }
.owbw{ overflow-wrap: break-word; }

#green {
  position: absolute;
  background: green;
  z-index: 1;
  width: auto;
}
</style>

<p>Test passes if there is a green rectangle below and no red.
<div id=green>X<br>X</div>
