During DnD, the region uses the 'old/current' midi_stream_view()'s range and its position/height calculation. Ideally DnD would decouple the midi_stream_view() for the region(s) being dragged and set it to the target's range (or in case of the drop-zone, FullRange). but I don't see how this can be done without major rework. For now, just prevent visual bleeding of events in case the target-track is smaller.
