Reopening the world map after zooming out showed the old map for a frame before the current zone.
In 1.12.1, every Lua verb that moves the map selection (`SetMapZoom`, `SetMapToCurrentZone`, a `ProcessMapClick` hit) goes through the setter `0x4a67a0`. The setter stores the selection, rebuilds the landmark list, then fires `WORLD_MAP_UPDATE` in place before returning (`0x4a6ce4`). So `WorldMapFrame`'s OnShow repaints the tiles before the first draw.
benilla queued the event to the next tick, so the first frame painted the previous map. The three verbs now run the setter whole. The landmark list is projected from per-row sources inside the setter, so the new tiles never show the old map's markers. The engine's own pushes still queue, as a narrowed deviation.
Tests replay the report's steps on the stock UI and check the event fires inside the verb with landmarks rebuilt first; they fail before the fix.
