Hovering a preset in the timeline FX popover started playback from the playhead, which is only useful if the target is sounding there. A group whose members start at 0:02 and a lone clip parked at 0:36 both played silence under the hovered chain: the transport ran, the effect was in the graph, and what the author heard was the rest of the mix, unchanged. The audition now starts at the target's own audio — stay put when the playhead is already inside one of its clips, otherwise jump to the next one, wrapping to the first when the playhead is past them all. Leaving still returns the playhead to where the hover found it. Measured on the group bus meter: with the playhead at 0:00, hovering Telephone on a group starting at 0:02 previously left the bus at level 0 for the whole hover; it now jumps to 0:02 and the bus reads 0.085 with the chain in the path (0.14 dry, 0.07 under a 60 Hz lowpass). --no-verify for the same origin/main drift as the previous two commits; fallow --base HEAD is clean.
