text (source code) displayed in browser that is in a <div style="white-space:
pre;"> block cannot be cleanly copied and pasted.  When pasted, the whitespace
characters are stripped away so the paste result is formatted in a contiguous
block, without streams of whitespace -- paste result looks very different from
what was seen in browser.  Same source code inside a <pre> tag block, on the
other hand, can be copied and pasted fine -- the paste carries forward all the
whitespace characters and pasted code is formatted just like what was seen in
the browser.  I duplicated this in Mozilla 1.7.1 also.  IE6 doesn't have this
problem.

Reproducible: Always

Steps to Reproduce:
1. See enclosed html file
2. Separately copy and paste each of the 3 blocks of source code from the
example into an editor.
3.

Actual Results:  
pasted source code has most of the whitespace removed.

Expected Results:  
make the paste result look like what I saw in the browser.  white-space: pre
should work like <pre> tag in this respect.

HTML file that illustrates the problem:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
   "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
    <title>test</title>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1" />
</head>

<body>

<div style="white-space: pre;">
  white-space: pre;
  for (i = 0; i < anchors.length; i++) {
       if ((anchors[i].className == "ln") || (anchors[i].className == "ln_hit")) {
           savedAnchorValues[i] = anchors[i].firstChild.data;
           anchors[i].removeChild(anchors[i].firstChild);
       }
  }
</div>

<div style="white-space: pre;">
    white-space: pre; with &lt;br/&gt; at end of each line:
    for (i = 0; i < anchors.length; i++) {<br/>
        if ((anchors[i].className == "ln") || (anchors[i].className ==
"ln_hit")) {<br/>
	    savedAnchorValues[i] = anchors[i].firstChild.data;<br/>
	    anchors[i].removeChild(anchors[i].firstChild);
        }<br/>
    }<br/>
</div>

<div>
<pre>
  &lt;pre&gt; tag:
  for (i = 0; i < anchors.length; i++) {
       if ((anchors[i].className == "ln") || (anchors[i].className == "ln_hit")) {
           savedAnchorValues[i] = anchors[i].firstChild.data;
           anchors[i].removeChild(anchors[i].firstChild);
       }
   }
