The filter freaks our when there is ">" in one of the attributes

When a user insert a text with a link and that link have the title attribute which contains ">" the filter freaks out. For eaxmple:

<a href='http://google.com' title='Foo >'>Google</a>

The text turns out to be:
<a href="http://google.com">'&gt;dasdasd</a>

Which looks like
'>dasdasd

That comes from _wysiwyg_filter_xss_split which the REGEX pattern try to find where the html element breaks and thinks the ">" in the title attribute and then break the html tag.
