Hoverlabels in stacked area charts with ggplotly not working properly

Hello there!

When creating a stacked area chart with ggplot in R and using ggplotly to create a plotly version of it, there occurs a rather grave error: in the hoverlabel only the frist value for each trace is shown. Say, I have years on the x axis, then for all years 2019 will be displayed, even though the value belongs to 2023.

My minimum code sample is here: https://plotly.com/ggplot2/filled-area-plots/

The official tutorials samples show the same behaviour on my Linux machine, all packages up to date.

Would really enjoy it if that were to be fixed!

Best regards!

从 issue 中链接的最小示例 https://plotly.com/ggplot2/filled-area-plots/ 开始，使用当前的 packages 重现堆叠面积图。跟踪 ggplotly 如何为堆叠的 traces 构建悬停标签；完成的标准是每一年显示属于该年的值，而不是 trace 中第一年的值。
