Sizing facet label size with guide-label fails

[eibanez]

I am trying to format all titles and labels in the plots, using guide-title and guide-label as recommended in the documentation.

I haven't done exhaustive checks but from the example below you can see that the size for facet row and column label names do not respond to the size property.

{
  "$schema": "https://vega.github.io/schema/vega-lite/v2.json",
  "name": "trellis_barley",
  "data": {"url": "data/barley.json"},
  "mark": "point",
  "encoding": {
    "row": {
      "field": "site", "type": "ordinal"
    },
    "column": {
      "field": "year", "type": "ordinal"
    },
    "x": {
      "field": "yield", "type": "quantitative",
      "scale": {"zero": false}
    },
    "y": {
      "field": "variety", "type": "ordinal",
      "scale": {"rangeStep": 12}
    },
    "color": {"field": "year", "type": "nominal"}
  },
  "config": {
    "style": {
      "guide-title": {
            "fill": "red",
            "fontSize": 15,
            "fontStyle": "italic"
        },
      "guide-label": {
            "fill": "blue",
            "fontSize": 15,
            "fontStyle": "italic"
        }
    }
  }
}
