In the course participants page, selecting an initials filter in one course and then moving to another (the filter would propagate) could result in few or no results being displayed. The teacher would then have no way of resetting the filter and viewing all (or possibly any) participants. Fixed by making each course participant page independent. They no longer share sort orders, collapsed column state, or initials filters.
