Summary: purge fails in IE6 if base tag is self-closing
Description:

The statement h.removeChild(node) of Y.Get._purge fails in IE6 with "htmlfile: Invalid argument." if the document head contains a self-closing base tag:



<base href="http://example.com/bug.html" />

It's obviously an IE6 defect, but the bug was difficult to diagnose so I'd like to make a record of it for other YUI users. The workaround is simply to explicitly close the base tag:



<base href="http://example.com/bug.html"></base>

Type: defect Observed in Version: 3.0.0
Component: Get Utility Severity: S4 (low)
Assigned To: Adam Moore Target Release: 3.2.0
Location: Library Code Priority: P3 (normal)
Tags: Relates To:
Browsers: IE 6.x
URL:
Test Information:

Steps to reproduce:
1. add a base tag to the head but do not explicitly close it with </base>
2. Y.use modules with a total of more than purgethreshold script dependencies, without combining requests.

I initially reproduced this with a valid XHTML document. For brevity here's the minimal HTML to reproduce this, with an implicitly-closed base tag:



<html>

<head>

    <base href="http://example.com/bug.html">

    <script type="text/javascript" src="http://yui.yahooapis.com/3.0.0/build/yui/yui-debug.js"></script>

</head>

<body>

<script type="text/javascript">

    YUI({ combine: false }).use('anim', 'datasource');

</script>

</body>

</html>

Need to test to see if the problem occurs when the nodes are inserted and removed above the self-closing base tag.
