Pressing up/down in focused frame list makes playback ignore inherited Fxx commands.

Repro:

1. Add F02 effect in a single pattern
2. Add a bunch of other patterns without F02
3. Playback first pattern, plays with F02 speed
4. Playback second pattern, plays with F02 speed
5. Playback first pattern, double clicking frame and pressing down
   Result: The frame changes and the speed changes because the F02 effect from a previous pattern is ignored
   Expected: The pattern changes and the speed doesn't change

(F02 is in 01 in dpcm)
