tip+brush combination by Fil · Pull Request #2361 · observablehq/plot
If tooltip is already visible (hovering near a point) and I start brushing, that last tooltip remains visible. I expected the tooltip to disappear as soon as I start brushing. Clicking after brushing removes the lingering tooltip, and I'm able to hover to show the tooltip again. I would expect to be able to see the tooltip on hover immediately after I release the brush, without requiring the additional click.
