	Replace #26661, fix #25979 Not perfect, but usable and much better than before. Since it is quite complex, I am not quite sure whether there would be any regression, if any, I will fix in first time. I have tested the related pages many times: issue list, milestone issue list, project view, user issue list, org issue list.
