Description:
------------
The "background" attribute of a <table>-tag causes the script to be executed twice.

This also happens if the script is nested somewhere in included sub-scripts, causing the calling main script to be executed twice, e.g.:

main.php includes sub1.php
sub1.php includes error.php

error.php has a <table background=...>

will result in a successive GET request, causing main.php to be executed again.

This occurs on Apache 1.3.27, both on Linux and Windows environment, tested with Internet Explorer 6 and Mozilla (Firebird). 
Apache and Php are running at the default configuration, no additional modules.

Reproduce code:
---------------
test.php:
-------------------
<html>
<body>
<table background="#FFFFFF">
	<tr><td></td></tr>
</table>
</body>
</html>



Expected result:
----------------
Should execute script once, which it does if the "background" attribute is removed.

Actual result:
--------------
Script will be executed twice, as described above.
