Office importer doesn't filter the meta and title tags from the pasted text

Follow this steps to reproduce:

• copy some plain text from OpenOffice Writer (I used 3.0.1) and paste it into the WYSIWYG Office Importer dialog
• inspect with Firebug the pasted content, before clicking "Import"; I got:

  <meta http-equiv="CONTENT-TYPE" content="text/html; charset=utf-8">
  <title></title>
  <meta name="GENERATOR" content="OpenOffice.org 3.0  (Unix)">
  <style type="text/css">
  <!--
  	@page { margin: 0.79in }
  	P { margin-bottom: 0.08in }
  -->
  </style>
  <p style="margin-bottom: 0in;">abc</p>
  

• click "Import" and inspect with Firebug the result; I got:

  <meta content="text/html; charset=utf-8" http-equiv="CONTENT-TYPE">
  <title></title>
  <meta content="OpenOffice.org 3.0  (Unix)" name="GENERATOR">
  <p style="margin-bottom: 0in;">abc</p>
  

As you can see the style tag has been filtered but not the meta and title. Also, I removed a lot of white space to keep the example clear. I think this white space should be removed by the importer through cleaning. I've seen cases where the browser behaves strangely in edit mode around text nodes like "\n\n\n\n".
