Hovering line excluded from tooltip triggers hover for other lines

[olsonjb]

Provide a general summary of the issue here

Hovering a line that is excluded from the tooltip via excludeDataKeys will trigger hover on the nearest non-excluded line. This issue was surfaced by @c-lamoureux in this thread

🤔 Expected Behavior?

Do not trigger hover from disabled line

😯 Current Behavior

disabledLineHover.mov

💁 Possible Solution

Reason for the bug:

To disable the tooltip interaction, the disabled line is excluded from the voronoi calculation

If the disabled line was still included in the voronoi calculation, we could end up with weird "dead" areas. None of the areas around the gray line below would trigger a hover - this could be problematic if lines or points overlap.

There may not be a good solution for this - just documenting the issue around Connor's comment in case we decide to investigate it more thoroughly in the future.

I don't totally agree that this is a bug and think we should discuss further. The points have been excluded from the tooltip and since chart types like line and scatter use voronoi to highlight the nearest point, if a point is excluded I think it should be excluded from the voronoi calculation.
I'm open to other opinions on what the expected behavior should be though.
