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.

https://jsfiddle.net/au7jgfkw/24/ の再現可能な例から始め、別々のグラフで行われる3つの Plotly.extendTraces 呼び出しを調べてください。各呼び出しの後の軸データを比較し、呼び出しを then コールバック内にネストすると結果が変わるかどうかを確認してください。繰り返し更新しても各グラフの軸データが分離されたままになることが完了の条件です。
