Updating style leads to error "undefined (reading 'get')"

**mapbox-gl-js version**: 2.82

**browser**: latest Chrome or Safari, happens on both

### Steps to Trigger Behavior

1. Click button in top left in code sandbox. Simulates update to style that causes the crash.

### Link to Demonstration

https://codesandbox.io/s/proud-wave-gohost

### Expected Behavior

Should not crash. This version doesn't do much but it crashes specifically with a symbol layer (I've found no other types of layers to be an issue).

### Actual Behavior

```
new LayerPlacement
../src/style/pauseable_placement.js:23:50
20 | _bucketParts: Array;
21 |
22 | constructor(styleLayer: SymbolStyleLayer) {
> 23 | this._sortAcrossTiles = styleLayer.layout.get('symbol-z-order') !== 'viewport-y' &&
| ^
24 | styleLayer.layout.get('symbol-sort-key').constantOr(1) !== undefined;
25 |
26 | this._currentTileIndex = 0;
```

Start with the CodeSandbox reproduction and then read src/style/pauseable_placement.js around the LayerPlacement constructor, especially the symbol layer layout access. Confirm the crash when updating the style with a symbol layer, and consider the issue resolved when that update no longer crashes in the reported browsers.
