Bug 19680 – cvs.com - the footer content is displayed over main content

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: Layout and Rendering

[Pat]

Go to http://www.cvs.com, then select the "Extra Care" tab.

Then footer content (contact us, etc) is displayed at the top of the page and over the main content. See attached screen shot.

This occurs on both Safari MacOS v3.1.1 (5525.18) and Safari for Windows v3.1.1 (525.17).

Main html of reduced test case

[Yael]

Created attachment 22014 [details]
external JS for reduced test case

[Yael]

The root cause of this problem is that when we have an external script that generates another script with document.write and the closing tag of the inline script is on the same line as more content, we process the document.write out of order.
The HtmlTokenizer keeps the remaining src as currentPrependingSrc and does not process it until later. This out of order processing is causing the problem.

The offending line is 
document.write('</script><table border="0" cellpadding="0" cellspacing="0" width="443"><tr><td align="left">');

If we split this line into 2 separate document.write statements, everything works fine.


I added an attachment of a very simple page where the content is processed in the wrong order.
