Multiple extendTraces calls causes axis data to mix

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:

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.

从 https://jsfiddle.net/au7jgfkw/24/ 中的可复现示例开始，检查三个独立图表上的 Plotly.extendTraces 调用。比较每次调用后的坐标轴数据，并验证将调用嵌套在 then 回调中是否会改变结果。完成的标准是，重复更新后每个图表的坐标轴数据仍保持隔离。
