In the task table on a bug page, each of Affects, Status, Importance and Assigned to have some text plus a disclosure triangle.
In every case the disclosure triangle unfolds the form to edit the task. For the Affects and Assigned to text, the text links to the bugs homepage for that product, distro, package, person or team.
However, for status and importance it unfolds the form.
This is inconsistent with the other fields. It seems unnecessary because there are already at least four controls to unfold the form. And it misses a useful opportunity to link to a list of other bugs having the same status or importance respectively.
