  <title>CSS Text: wrappable ('break-spaces') inline inside a 'white-space: pre' block</title>

  <style>
  div
    {
      border: black solid 2px;
      font-family: monospace;
      font-size: 32px;
      margin-bottom: 0.25em;
      width: 16ch;
    }

  <p>Test passes if the characters inside of each black-bordered rectangles are laid out identically.

  <div id="test">Lorem ips<span>um.      Dolo</span>r
   sit&Tab;amet.</div>

  <div id="reference">Lorem ipsum.&nbsp;&nbsp;&nbsp;&nbsp;<br>
&nbsp;&nbsp;Dolor<br>
&nbsp;&nbsp;&nbsp;sit&nbsp;&nbsp;amet.</div>

<!--

  <div id="test">Lorem ipsum.      Dolor
                             ^^^^^^
                             123456

   sit&Tab;amet.</div>

123


Since 'tab-size' is by default 8,
since "sit" uses 3 characters
and since there are 3 preserved
white space characters before "sit",

then the horizontal tabulation will use as much space
as a sequence of 2 preserved white space characters.


  &Tab; == Horizontal tabulation == &#x0009; == &#09;
