[Support] Delete item from chart and updating doesn't hide tooltip

[ChaseLewis]

Is there a function to call after update() so the tooltip hides itself? On click I'm finding the corresponding element in a scatter plot and deleting it from the chart, then refreshing the chart. However, the tooltip doesn't hide itself when calling update even though the point is no longer in the dataset. I'd like to hide it manually so it doesn't linger around if possible. Any assistance on how this could be accomplished as I don't see how to in the API?

I dont' want to disable tooltips altogether, just hide the currently showing one.

@ChaseLewis good question! You might get away with doing chart.tooltip.initialize() like is done inside of reset() https://github.com/chartjs/Chart.js/blob/master/src/core/core.controller.js#L334 but there is no guarantee that chart.tooltip would be around forever since it's meant to be internal.

That'll work. Very much appreciated. If it is deprecated i'd consider maybe a show / hide feature for a given element. Might be nice to trigger it on & off from another control like a data grid or something like that.

Just a note you need to call the chart.resetElements first since initialize looks at the active elements in the chart among other things to decide what its initial state is.
