gpui delivers DragMoveEvent to every drop target with a matching payload type under the cursor, and every slider shared the SliderDrag payload type — dragging one slider (e.g. an OFX panel parameter) also moved every other slider the cursor passed over (timeline zoom, track height). Tag the payload with the starting control and ignore drag moves that are not ours. Also finish the gesture on mouse-up (inside or outside the track) instead of on_drop: gpui only delivers drop events to the hovered target, so releasing outside the track used to leave the drag unfinished and the final value/undo edit unemitted.
