<meta name="assert" content="Preserved white space with pre-wrap at the end of a line ending with a forced line break conditionally hangs, so it does affect alignment.">

<style>
div {
  white-space: pre-wrap;
  font-family: monospace;
}
div:nth-of-type(2) {
  width: 7ch;
  text-align: right;
}
div:nth-of-type(3),
div:nth-of-type(4) {
  width: 9ch;
  text-align: center;
}
</style>

<p>This test passes if the 4 letters below are verticaly aligned.

<div>    P</div>
<div>A  </div>
<div>    S                                </div>
<div> S </div>
