The issue you're experiencing, where the line chart legend resets to the first page when selecting a dimension on another page, seems to be related to how the legend state is managed in the Superset line chart component. Unfortunately, I couldn't find specific information in the repository about the logic behind resetting the legend to the first page or how pagination is implemented in the legend.

However, the event handlers legendselectchanged, legendselectall, and legendinverseselect are triggered when a dimension is selected in the legend. These handlers call the onLegendStateChanged function with the payload.selected parameter, which might be related to the behavior you're observing ^[1].

To address this issue, you might want to investigate how the onLegendStateChanged function is implemented and whether it affects the pagination state. Additionally, reviewing the component's state management logic, particularly how it handles legend interactions, could provide insights into why the legend resets to the first page.
