setting 'temporal' and 'bin' crashes editor

[MarcBaeuerle]

I tried using type: "temporal" and "bin": { "step": 1 } in the same config and my editor instantly crashed when loading.

Only use this spec in incognito

so it doesn't get stored locally. Otherwise, the vega editor will crash before you can change anything.

{
  "data": {"url": "data/seattle-weather.csv"},
  "mark": "bar",
  "encoding": {
    "x": {"timeUnit": "month", "field": "date", "type": "temporal", "bin":  {"replace_me": 1} },
    "y": {"aggregate": "mean", "field": "precipitation"}
  }
}

replace relace_me with step to reproduce

I think bin takes precedence and then you can a bin for each 1 in a timestamp (which is very large). I'd say that's somewhat expected. I'm not sure what the right behavior in this case should be. Maybe ignore bin?
