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.

hi! can I help with this? @rowanwins

hey @rowanwins we are a group of students working on a software maintenance and evolution project. we are interested in working on this feature. We would like to explore extending the interaction handling so that tooltips can remain visible when the cursor moves from the data point to the tooltip area. we are considering approaches such as extending the interaction region or handling tooltip hover events.
please let us know if it’s okay for us to proceed. thanks..
