Area chart hover does not fire tooltip when tooltip grouped is false

I noticed when the tooltip is set to grouped: false, the user is required to hover on the point to show the tooltip. This is an issue if the point is very small or the user wants this functionality on the area chart data areas.

On an Area chart, the hover effect does not fire on the specific data of the area when tooltip grouped is false. Only the tiny point.

Is there a way to add .focus or create a function that fires on hover of the whole area instead of just the point?
