Status: RESOLVED DUPLICATE of bug 296921

(Core :: DOM: Core & HTML, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.8.1.12) Gecko/20080201 Firefox/2.0.0.12
Build Identifier: 

See the attached testcase.

The JavaScript in the testcase creates a <pre> element. However, it is rendered as if it was a <div>.

Reproducible: Always

Actual Results:  
<pre> element is rendered as if it was a <div>, even though "View selection source" actually shows the element as a <pre>.

Expected Results:  
<pre> should be rendered as a <pre>.

This problem occurs only if the document's MIME type is text/xml. If it is text/html, the code works as expected.

Attachment: Same file with text/html and without CDATA - bug no longer occurs

Whoops? Looks like the HTML parser doesn't like CDATA ... but anyway, this one works, this is what it should look like.

Use createElementNS and/or application/xhtml+xml.
