User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031007 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.5) Gecko/20031007 Have a look at the URL http://test.indexdata.dk/sondberg/error.html The content of the textarea field should be <P></P> but is rendered as <P></p>. The same applies to the <BR></BR> constellation while the <TEST></TEST> constellation works as expected. It looks like the browser inserts HTML elements differently from other elements. What makes this bug extra weird is that <P></P> is internally in Mozilla converted into <p></p> and likewise with <BR></BR>, while no conversion takes place for <TEST></TEST>. Reproducible: Always Steps to Reproduce: 1.Load the Mozilla browser 2.Point the browser at the URL http://test.indexdata.dk/sondberg/error.html 3.Compare the content of the textarea field with the source code of the web-page 4.Eventually, try to connect directly to the web-server with telnet, i.e. % telnet test.indexdata.dk 80 GET /sondberg/error.html HTTP/1.1 <return> Host: test.indexdata.dk <return> <return> 5. Compare the result with (2) and (3). Actual Results: The content of the textarea field is this (in the browser window): <P></p> <BR></br> <TEST></TEST> The corresponding client side HTML source code reads: <p></p> <br></br> <TEST></TEST> And the original server side HTML reads: <P></P> <BR></BR> <TEST></TEST> Expected Results: Two different issues confused me: 1) Mozilla converts capital html elements, i.e. <P></P> and <BR></BR> to lowercase elements, i.e. <p></p> and <br></br>. I expected no case conversion at this stage! This issue, however, is not really a problem for me in itself. 2) Mozilla seems to render <P></P> as <P></p> and likewise for a collection of other empty HTML elements, where I expected <P></P> to be rendered as <P></P> etc. Especially, issue no. 2 is frustrating, because it eventually breaks XML well-formedness. I can add that I've been able to demonstrate the bug in Mozilla 1.2 and 1.5 on windows, and 1.5 on Linux. Internet Explorer as well as Konqouror don't have this problem.
Confirmed on WinXP trunk 2003102004.
OS: Linux → All
Source code should be escaped. Save the file as .xhtml (content-type = application/xhtml+xml) and you will see that the textarea is empty. I can add a test case which demonstrates this if you want. But it is invalid, so I think you can't predict then, what will happen.
