For operators that depended on working on the data of 'selected' channels, but which needed to get F-Curves only, collapsed groups posed a problem (these operators included inserting keyframes on selected channels only, pasting keyframes, and ghosting curves).
When these groups were selected, all their F-Curves should get included regardless of selection since it's too confusing otherwise. However, inside the F-Curve filtering code, selection was still being considered. This problem has now been avoided by not filtering the F-Curves for selection status in these cases.
