Issue metadata are misplaced
Votes, assignee, milestone and tags are now placed next to comments. It makes no sense, these metadata are related to the issue, not to the comments. And as you can see on attached screenshot, tags are not visible now without scrolling.
Milestone should be in issue header. Assignee may be listed next to participants. Tags should be in-line just under the issue body. Votes can be placed right of the tags (on the same row, float right).
After removing the right column, comments will get much more space.
