Description
I was trying to create a plot, with 8 tracks divided in 2 subplots arranged in a grid, where 7 tracks share same x axis and one of them will have a different x axis. here is sample
var data = [{

I am unable to figure out why track with name "Channel 5" is hiding other tracks behind it, while xaxis2.overlaying is set to 'x' and yaxis6.overlaying = yaxis4.overlaying = yaxis8.overlaying = 'y2'.
here is screen shot.

First steps
- Read the whole issue, then the project's contributing guide.
- Comment on the issue to say you are picking it up — it saves two people doing the same work.
- Fork the repository and make your change on a branch.
- Open a pull request that references the issue number.
Research direction
Start by reproducing the example from the linked CodePen and the Plotly.newPlot call, focusing on how Channel 5 and xaxis2.overlaying interact with the grid. Compare the rendered tracks with the supplied layout, then trace the overlay behavior until the cause of Channel 5 hiding other tracks is identified. Done means the reproducer preserves all tracks while retaining the intended overlaid axes.
