Dropped markers render only on 3D Globe (Photoreal), not on 2D maps

[jfuginay]

Markers dropped by the user show on the 3D Globe (Photoreal) but never appear on the 2D map styles.

Expected: markers render on every engine/style.

Likely area: 2D MapLibre contact/marker layer not receiving locally-dropped CoT events (works on the Cesium bridge path, fails on the MapLibre path).

Reported by u/mozios on the r/ATAK tester thread: https://www.reddit.com/r/ATAK/comments/1u2ef0u/comment/or3e9d0/ (build era: 0.35.x closed testing, June 2026). Tester also praised performance/fluidity, interface design, the 3D Cesium view, and code structure.

Reopening — tester mozios confirms on v0.35.5 (Pixel 9 Pro, which already includes the #91 fix from 0.35.4) that dropped markers still don't render on the 2D map. Root cause is a GPU repaint issue: setGeoJson pushes the data but the layer doesn't repaint until a full style reload. #91 fixed a style-load race, not the repaint.
