User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.3a6pre) Gecko/20100611 Minefield/3.7a6pre

Use of <strong/> still allows the text to be bold after it.  Though the proper use of <strong> </strong> should be used.

Testcase coming up.

Reproducible: Always

Actual Results:  
The rest of the text is rendered as strong text.

Expected Results:  
Work around parsing errors like this.

Could the parser ignore invalid tags?  What does W3C spec say about it?

Henri, do you have an idea on what the proper way to handle bad tag use is?

Everything about the content (parsing, networking, layout, images) are Core

This is expected behaviour.
<strong/> is the same as <strong> in HTML, the slash is ignored. (HTML is not XML)

Thanks guys, It wasn't obvious to me what the issue was.  I been trying to figure that out how it fits together and why it was still parsed when you think it should be something else by viewing it than what its allowed to do.
