Polar Area multiple dataset hover hitboxes are misplaced

[Kwonunn]

Expected behavior

When hovering over a slice in a polar area chart with multiple datasets, the slice you hover over should highlight and display its tooltip.

Current behavior

In certain spots of the chart, a different slice gets highlighted and tooltipped.

Just use pie chart instead. In polarArea, each arc starts from the center, and thus are overlapping.

When changing the interaction mode to 'point' for example, multiple arcs are hovered:
