After performing a map resize with certain map dimensions in Chrome, parts of the map are left gray (unloaded)

Nobody has claimed this yet.

**mapbox-gl-js version**: 1.12.0

**browser**: Chrome 87.0.4280.88 on Mac

### Steps to Trigger Behavior

1. Load the page. This page is configured to wait until the map is loaded, then wait 1 second more for good measure, then attempt to resize the map.
2. The left-hand side of the map appears gray and unloaded, as if some tiles are missing.

### Expected Behavior
The map loads normally.

### Actual Behavior
The left-hand side of the map appears gray and unloaded, as if some tiles are missing.

Start with the linked JSBin reproduction and investigate the map resize path after the map-loaded wait, using the reported Chrome version and map dimensions. Done means the demonstrated resize leaves no gray or unloaded regions and the map renders normally.
