Description
Axis data becomes mixed between graphs when using Plotly.extendTraces on more than one graph on a page.
You can find a reproducible example below:
https://jsfiddle.net/au7jgfkw/24/
Screenshot of the bug in question:
As you can see, the first graph works as in tended. However, the proceeding two graphs contain the axis data related to another graph. Running the three lines of extendTraces further mixes the data between the graphs.
I have also tried nesting subsequent extendTraces calls in a .then callback to ensure that each line is called synchronously. However, this yields the same result.
I have also created a post on Plotly.js forums regarding this bug 25 days ago, but it does not have any comments.

Research direction
Start with the reproducible example at https://jsfiddle.net/au7jgfkw/24/ and inspect the three Plotly.extendTraces calls on separate graphs. Compare the axis data after each call and verify whether nesting calls in a then callback changes the result. Done means repeated updates keep each graph's axis data isolated.
