Dropped rendered features drag panning the globe

I noticed while dragging panning the map down as far as it would go, geometry features no longer render correctly or are dropped from the map entirely:

**Version**: `2.9.1`

No source files, tests, or entry points are named. First reproduce the issue in mapbox-gl-js 2.9.1 by dragging the globe downward as shown, then trace the rendering path involved in dropped geometry. Done means features remain rendered correctly at the lowest panning position.
