/**
 * Dev-only: repro + regression check for the MAP console's object click.
 *
 * Scenario under test:
 *   1. open the map console (deck MAP button)
 *   2. hover a discovered object on the chart → the tooltip
 *      (name + "TAP TO PLOT COURSE") must be part of the window
 *   3. click it → autopilot (ship.target set)
 *   4. close the map → NOTHING of the tooltip may linger on screen
 *
 * The known bug: ttPlate/ttName/ttSub/ttHint are created with
 * scene.add() but never added to the MapWindow container (only the
 * EMPTY ttCont is) — so they paint at depth 5, BEHIND the window
 * (depth 80), and survive close() (nothing ever hides/clears them).
 *
