I'm not sure this legitimately depends on bug 236839, because I can think of several ways for implementing this functionality without XBL and possibly even without JS. Anybody up to take on this bug?
Not "wanted" (by release-drivers) in the sense of a prospective blocker that we'll actively champion finding developers for. If a fix ever shows up we'll evaluate risk/reward if someone wants to drive it into the 1.9.0 branch. Your better approach would be to get a fix in a more recent branch first.
