From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; N; Linux 2.2.12-20 i686; en-US) Mozilla/m13
BuildID: 2000022916
(The User-Agent is wrong. I'm using Mozilla/m14)
If the <head> element of an html document contains an unclosed <title> tag, the
rest of the html document fails to display.
On the one hand, an HTML document with an unclosed <title> doesn't conform to
the spec, and so mozilla shouldn't have to display it correctly.
On the other hand it would be robust behavior to assume the <title> tag closes
when the </head> tag is seen.
Reproducible: Always
Steps to Reproduce:
1. Create a document with <title> tag in the header, but no matching </title> tag.
2. Load the document in mozilla M14 on linux
Actual Results: No page content is displayed. The debug output to the console
gives the following feedback:
FindShortcut: in='http://www.math.arizona.edu/~jsac/test-title-bug.html' out='null'
failed to set the page title.
Document http://www.math.arizona.edu/~jsac/test-title-bug.html loaded successfully
Document: Done (0.499 secs)
Expected Results: Assumed the </title> tag when it saw </head> and displayed
the contents of the page normally.
The following html demonstrates the problem succinctly:
<html><head><title></head><body>
<h1>You should not see this.</h1>
</body>
</html>

Confirmed on 2000042113, Linux.
Sounds more like a bad HTML problem to me, but hey like the author said, the
browser should be more "robust."

<tough_decision>Nav4 doesn't display the contents of this page either.
Therefore, this bug is an enhancement request to handle very bad HTML better
than Nav4. Both bad HTML & something Nav4 didn't handle --> low priority.
Marking enhancement and FUTURE.</tough_decision>
Severity: normal → enhancement
Target Milestone: M17 → Future
Nothing tough about it. It's broken input, IE and nav dont do it, so we don't
either. Marking wontfix.
