Description
I was trying to use the multi-axes functionality in Plotly with the tickmode='sync' option, but the result was not as I expected. The grid axes are not aligned at y = 0 and the ticks of the second y axis are not "nice" rounded numbers. I found out that this issue was already raised in the repository where the functionality was originally pulled from: https://github.com/VictorBezak/Plotly_Multi-Axes_Gridlines/issues/4. Unfortunately, it was never resolved and since it is incorporated in Plotly I think it would make more sense to raise the issue here. Hopefully, someone can help me out!
P.S.: I think issue https://github.com/plotly/plotly.py/issues/4351 is referring to the same problems, but it is not as nicely explained as the issue mentioned above.

Research direction
Start by reproducing the multi-axes case with tickmode='sync', then compare the behavior with the linked upstream issue and plotly.py issue #4351. Done means the grid axes align at y = 0 and the second y-axis uses nice, rounded tick values.
