It's appropriate behavior for an HTML browser.  In HTML, a funny
character like /> indicates the premature end of a tag, and thus
"something else."  In a <head> statement, you can't have free-floating
character data outside of an element.  So this is (properly, I
believe) interpreted to mean "we've reached something which isn't
<head>, so this must be <body>, with both the closing tag for
<head> and the start tag of <body> left off."  (Recall that in HTML,
closing and opening tags for <head> and <body> are optional, and
will be inferred if they are not provided.)

And so the /> is the start of your body content, so it gets displayed.

This is a case where XHTML -- even XHTML written according to the
W3C's guidelines for proper compatibility, e.g. spaces before the
/ -- can cause problems in HTML-compliant browsers.  XHTML is _not_
designed to be 100% backwards-compatible with HTML browsers, only
about 99.44% compatible.
