Mixed chart with stacked bars - incorrect max height

Explanation

• What is the behavior you expect?
  Following Stacked Bar Graph with Line?  #26, In mixed chart type, should be able to have stacked bars, without affecting how the line and area chart types and have correct max height of the graph.
• What is happening instead?
  If enabling the stacked chart as in the example code pen, the max height is to big.

This is still using the sum of all the values as the max of the yscale, when it shouldn't. Maybe adding a different axis would help?

Hi, I'm experiencing the same issue with stacked bar + line combo, where the max height is incorrect (too big).
When displaying the bars as lump sum, the max height is correct.
Did anyone find a workaround? I've tried to manually set the max but that messes with the forceNiceScale parameter of the y-axis.
