See the given revision. I forgot to add "tl|" in the last section title. The parser didn't give an [edit] link for the last section (section 47), but when I clicked the [edit] link for section 46, it didn't give me the wikitext in section 47, which could be edited (getting wikitext and saving) with section=47 if I typed it manually.
The headline in question is <pre> == 本地{{hideH}}模板使得没有鼠标的用户无法阅读其中内容 == </pre> The {{hideH}} template is comparable to en.wiki's Collapse DIV's things. I asume the reason for this is because it's adding a block level element, thus the [edit] link can't be added anywhere good. however it is interesting that section=n manually does work. Presumably because the code for section=n looks at the source code directly and find a perfectly fine == heading == there.
I guess the normal renderer doesn't recognize that 'section' as a section because it's even not in TOC; not knowing where to put the link is not a blocker. However, the parser used for §ion= recognizes that 'section' as a section, which leads to this bug.
Another case: http://zh.wikipedia.org/w/index.php?title=Wikipedia:%E4%BA%92%E5%8A%A9%E5%AE%A2%E6%A0%88/%E5%85%B6%E4%BB%96&oldid=13703709 where the section title is == [[mw:Extension == The parser renders it as a section (uses <h2>), puts it in TOC, but doesn't give it an [edit] link. &action=edit§ion= doesn't treat it as a section.
Some more cases: == {{ ==
