Description:
------------
For some reason beyond my knowledge, the strip_tags function is
selectively stripping allowed_tags. I have tested it against three
relatively similar strings (all <embed> tags) and it passing on only
one out of the three. The string and xhtml tags themselves are
perfectly valid, and I have no clue why strip_tags is behaving in such
a way.

Reproduce code:
---------------
echo strip_tags('<embed allowScriptAccess="never"  
src="http://www.picturetrail.com/photoFlick/l_bookhorizontal.swf";
name="photoFlick"
