Display issues with subtasks according to priority

As a team-member or product owner
I want to see issues in the ongoing sprint ordered according to priority
so that I know what issue to fix next.

When I view the current sprint in my "Work-tab" (rapidBoard.jspa?...view=detail) I want to view all my items ordered with highest priority on top. This is true for issues without subtasks. If however, I have subtasks among the issues, those issues together with the subtasks are displayed on top. I cannot figure out their priority in relation to the other issues.
