                    executed when it is in iframe
           Product: WebKit

          Platform: PC
               URL: www.hoodboyz.de/shop

reduced testcase

I Steps:
Go to www.hoodboyz.de/shop

1. see for example www.hoodboyz.de/shop the left categorie selection box!
its a iframe to www.hoodboyz.de/shop/cat.php?schritt=&cat_id=  
2. when i  select a categorie,size or manufacturer the post don't contain 
the option values!
3. When i select directly from cat.php its no problem!

II Conclusion:
For original web page, it has javascript like:
......
<script
language="JavaScript">parent.location.href="index.php?cat=11";</script><script
language="JavaScript">parent.location.href="advanced_search_result.php?keywords=Free
Search";</script>
......
In webkit, the second sentence has a chance to be executed, this is the cause
of the issue.

In the iframe document test-standard.html, there are two javascript sentences:
......
<script>parent.location.href="http://www.google.com";</script>
<script>parent.location.href="http://www.yahoo.com";</script>
......

In IE and Firefox, the second sentence will have no chance to be executed, so
the page will be redirected to google.com, but in webkit the second sentence is
executed, so the page is redirected to yahoo.com.

III Other Browsers:
IE7: ok
FF3: ok
