scale independent conflicts with height

[krlng]

I use altair (see issue) to render a vega_lite Chart with two figures that have independent y-axis and different heights. How ever, the second height does not have an effect. The vega-lite JSON looks like:

{
	"config": {
		"view": {
			"continuousWidth": 400,
			"continuousHeight": 300
		}
	},
	"vconcat": [{
		"layer": [{
			"mark": "line",
			"encoding": {
				"color": {
					"type": "nominal",
					"field": "symbol"
				},
				"y": {
					"type": "quantitative",
					"field": "price"
				}
			},
			"width": 850
		}, {
			"mark": {
				"type": "area",
				"opacity": 0.4
			},
			"encoding": {
				"y": {
					"type": "quantitative",
					"aggregate": "average",
					"field": "price"
				}
			},
			"width": 850
		}],
		"encoding": {
			"x": {
				"type": "temporal",
				"field": "date"
			}
		},
		"height": 260,
		"resolve": {
			"scale": {
				"y": "independent"
			}
		}
	}, {
		"layer": [{
			"mark": "line",
			"encoding": {
				"color": {
					"type": "nominal",
					"field": "symbol"
				},
				"y": {
					"type": "quantitative",
					"field": "price"
				}
			},
			"width": 850
		}, {
			"mark": {
				"type": "area",
				"opacity": 0.4
			},
			"encoding": {
				"y": {
					"type": "quantitative",
					"aggregate": "average",
					"field": "price"
				}
			},
			"width": 850
		}],
		"encoding": {
			"x": {
				"type": "temporal",
				"field": "date"
			}
		},
		"height": 60,
		"resolve": {
			"scale": {
				"y": "independent"
			}
		}
	}],
	"data": {
		"url": "https://vega.github.io/vega-datasets/data/stocks.csv"
	},
	"$schema": "https://vega.github.io/schema/vega-lite/v4.8.1.json"
}

Can you simplify the test case? I don't see a problem in a simpler chart: Open the Chart in the Vega Editor.

[krlng]

I don't think so. I actually do not know much about vega-lite, the altair example is already as minimal as it can get to produce the error.

The test case is definetly to minimal, since the root of the problem seems to be the vconcat combined with the differing height attributes

[domoritz]

Ahh, here: Open the Chart in the Vega Editor.

[krlng]

Yes, thats the bug

[domoritz]

Somehow there is only a single height property. That is definitely wrong.

I have a fix that I will push in a second.
