<meta name="assert" content="Preserved white space at the end of soft-wrapped lines is hanged when white-space is pre-wrap, and therefore does not count when computing the (minimum) intrinsic size.">

<style>
div {
  font: 25px/1 Ahem;
  white-space: pre-wrap;
  width: min-content;
  color: green;
  background: red;
}
</style>

<p>This test passes if there is a green rectangle and no red.
