Stopgap fix for issue #5887 is missing ignoredFeatures

[ChrisLoer]

We filter out invalid results from the main collision grid, but not the ignored grid:

mapbox-gl-js/src/symbol/collision_index.js

Lines 279 to 292 in ea28e71

	const thisTileFeatures = [];
	const features = this.grid.query(minX, minY, maxX, maxY);
	for (let i = 0; i < features.length; i++) {
	// Only include results from the matching source, tile and version of the bucket that was indexed
	if (features[i].sourceID === sourceID && features[i].tileID === tileID && bucketInstanceIds[features[i].bucketInstanceId]) {
	thisTileFeatures.push(features[i].boxIndex);
	}
	}
	const ignoredFeatures = this.ignoredGrid.query(minX, minY, maxX, maxY);
	for (let i = 0; i < ignoredFeatures.length; i++) {
	if (ignoredFeatures[i].sourceID === sourceID && ignoredFeatures[i].tileID === tileID) {
	thisTileFeatures.push(ignoredFeatures[i].boxIndex);
	}
	}

I want to get a fuller fix for #5887 in, but we should probably get the stopgap fixed for .44.
