Stacked line area not working with toolbox enabled

[DebenOldert]

Version

5.0.2

Reproduction link

https://jsfiddle.net/rvauncdf/

Steps to reproduce

When using the toolbox, the top stacked line serie is not shown in the chart and thus the area between the bottom and top line of the stack is not shown. When the complete toolbox object is removed from the option, the area between the stacks is shown.

What is expected?

It is expected to show the area between 2 stacked lines, even then the toolbox is used.

What is actually happening?

The top series of the stack does not appear in the chart. So a series is missing and the area is not shown.

---

Sometimes when the difference between the 2 stack line series is larger, the serie and area will appear, however, it should appear at any value range
