Allow the tooltip to remain open on hover

Feature Proposal

Hi there,

I've got a slight issue with what I'm trying to achieve...

I'd like to be able to hover on my tooltip, but as soon as I move my cursor over the tooltip it disappears

I've tried playing with a few of the interaction modes but none quite do what I want, it's particularly problematic with a scatterplot.

Possible Implementation

I think ideally what I'm looking for is that the interaction covers the point and the resulting tooltip area, perhaps something like

    interaction: {
      intersect: true,
      mode: 'point+tooltip',
    },

It might be that this is best catered for by a custom interaction mode but I thought I'd flag it for feature consideration.
