In a mixed chart with an area chart and a line one, some values are totally wrong.
You can see an example below:

Jan 7th is supposed to display 12 (green) + 50 (yellow) but displays 100.
Furthermore, when toggling STACK1, it also changes the Y value of Jan 7th and 8th, even though they should not be affected.
You can see a fiddle here: https://jsfiddle.net/gcretfs0/
As you can see, I'm using V2.9.3.
