firstChild works incorrectly in some cases by using white space or return

Reproducible: Always

Steps to Reproduce:
1. test working example:
<code>
<ol id="Liste1"><li id="e1">Element_1</li><li id="e2">Element_2</li></ol>
<script type="text/javascript">
document.getElementById("Liste1").removeChild(document.getElementById("Liste1").firstChild);
</script>
</code>

also working:
<code>
<ol id="Liste1"> < li id="e1">Element_1</li><li id="e2">Element_2</li></ol>
<script type="text/javascript">
document.getElementById("Liste1").removeChild(document.getElementById("Liste1").firstChild);
</script>
</code>

and:
<code>
<ol id="Liste1">
<
li id="e1">Element_1</li><li id="e2">Element_2</li></ol>
<script type="text/javascript">
document.getElementById("Liste1").removeChild(document.getElementById("Liste1").firstChild);
</script>
</code>

2. but if you have a white space or return between ">" and "<li" 
it doesn't work:
<code>
<ol id="Liste1"> <li id="e1">Element_1</li><li id="e2">Element_2</li></ol>
<script type="text/javascript">
document.getElementById("Liste1").removeChild(document.getElementById("Liste1").firstChild);
</script>
</code>

or:
<code>
<ol id="Liste1">
<li id="e1">Element_1</li><li id="e2">Element_2</li></ol>
<script type="text/javascript">
document.getElementById("Liste1").removeChild(document.getElementById("Liste1").firstChild);
</script>
</code>




if you use 
document.getElementById("Liste1").removeChild(document.getElementById("e1"));
it works everytime
