It seems using the h1 tag in a wiki page causes issues with editing sections. These results are not seen with 1.6.8 but are seen with 1.7 and 1.8. Start out with: ==Heading 1== <pre> <h1>test</h1> </pre> ==Heading 2== If you click on Heading 2 to edit that section and then save that page you will get the result below. ==Heading 1== <pre> ==Heading 2== asdf In the example above I added the asdf when editing the second section, as you see data is lost. Editing section 1 creates even more strange results. Starting with the first example and editing section 1 I get the following output. ==Heading 1== asdf <pre> <h1>test</h1> </pre> <h1>test</h1> </pre> ==Heading 2==
More server information... MediaWiki: 1.8.2 PHP: 5.1.6 (apache2handler) MySQL: 5.0.24a-standard
Bug still remains in version 1.9 MediaWiki: 1.9.0 PHP: 5.1.6 (apache2handler) MySQL: 5.0.24a-standard-log
I also hit this problem (in version 1.9.2 and 1.9.3) but with h2 tags inside a pre. It seems that code generating the section [edit] links properly skips over the h2-inside-pre since it is rendered with the < and > encoded as html entities. However, the code saving the changes probably sees the raw text and counts this as a section boundary, thus saving and overwriting the wrong section!
Can confirm with 1.9, but seems fine on 1.10 w/ current trunk.
This is still an open issue with 1.10. All you need is a page with multiple sections, some of which contain <pre> areas. Then go to a section right after one with a <pre> tag in it, edit it, and add a new section, thus splitting the section in half. When you save it is almost always corrupted. Just tried this with 1.10RC1.
Just to confirm that the original example still has the same result on 1.10.0rc1.
I have tested with MediaWiki 1.5 through to trunk and can verify that it happens in all versions of MediaWiki higher than or equal to 1.7 (including trunk) - see http://www.wikitest.co.uk/1_6/Header_test, http://www.wikitest.co.uk/1_7/Header_test and http://www.wikitest.co.uk/SVN/Header_test
