0 not aligned when having multiple y axes with negative numbers

[mtadams007]

I have a plotly chart with lines and columns with both negative and positive values. The 0 on both y axes is at a different spot. It would be nice if there were an option in layout.yaxis where one could align the 0s without having to calculate the domain.

Here is a codepen illustrating the issue: https://codepen.io/mtadams007/pen/ByNgyjJ?editors=0010

The solution proposed in #1845 (comment) does not work as in that example both axes start with 0 and have no negative numbers.
