I was looking through the tag excerpts and I noticed the Etymology excerpt that appears on the Tags page doesn't match what appears on the tag pop-up tooltip, the etymology tagged questions page, or the etymology full wiki page's excerpt section.
I don't see anything that stands out as the reason, especially since tags like particle-ni and kana have both kana and parenthesis in the exerpt which shows up on the page. Some long excerpts are trimmed to three sentences on the Tags page, but that's not the case here either, because there's a full line open.
Is this a bug? Looks this way on both Chrome and IE.
