Was about to comment the same thing and still not corrected, I wonder if someone read the comments...
The admin occasionally reads the forums and corrects these manually, but as far as I can tell it's just one person in their free time, and there are probably hundreds if not thousands of these slightly misaligned furigana (since they're done programmatically).
I read all comments, but reply ... slowly :) It seems like I missed this comment when it was first written though. My bad.
You're right @Leebo, I work on Jisho in my free time. Recently, most of that time is spent on a new version of the site, but occasionally, like today, I try to get a few fixes in for this version.
This furigana is now showing as it should.
夢見る furigana wrong
I think it should read 夢(ゆめ)見(み)る, not 夢(ゆ)見(めみ)る
