I was trying to link part of an article on wikipedia - specifically this to refer to a specific section of the wikipedia entry. It quotes start of the article, as opposed to the part of the article I was trying to link to - it was a little confusing.
The onebox for this link
The section that the link actually points to.
Note that the link still works - it takes you to the correct section. But, the onebox implies it will go to the top-level article instead, which is confusing.
So... could we get oneboxes to be aware of sections in pages - they do seem to use a standard notation.
