Description
The in plotly.js 2.34.0 introduced zorder property does not work as expected. The following chart demonstrates the issue:

The orange line is drawn on top, but it should be drawn behind the green and red line.
The issue seems to be related to the traces being linked to different y-axes. Once the axes are being linked to the same y-axis, the bug disappears.
