Research direction

Start by reproducing the issue with the listed globe-view steps: high pitch, zoom past the Mercator transition, then pan until circles move farther away. Compare the expected Mercator and actual Globe recordings while tracing the circle rendering path around that transition. Done means circles remain visible at high zoom and pitch in Globe view.
