596559 - Title of XHTML documents not shown in tab or title bar if <title> element has a namespace prefix

Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Florian Lherbette]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8

The document title appears to be shown on the UI only if the <title> element is in the default namespace. I tested this with XHTML documents served either as application/xml or as application/xhtml+xml, on Firefox 3.6.8 on Linux and Firefox 3.6.9 on Mac OS X.

Title is displayed correctly with this kind of workaround:
<html:html xmlns:html='http://www.w3.org/1999/xhtml'>
  <html:head>
    <title xmlns='http://www.w3.org/1999/xhtml'>Title</title>
  </html:head>
  <html:body />
</html:html>

Reproducible: Always

I see this on 3.6, but not on Mozilla/5.0 (Macintosh; Intel Mac OS X 10.5; rv:2.0b7pre) Gecko/20100926 Firefox/4.0b7pre. Can you confirm this works in the Firefox 4 beta?

WFM using Firefox 50.0 on Windows. Minimal testcase attachment shows 'Title' from html:title element as expected (as well as any other string, such as 'foo', one puts in there
