Description
If hoverinfo of trace is set to skip , No event handler works.
Please see it: https://codepen.io/freddicola/pen/vYRemyN
I cannot understand why the hoverinfo is related to the event handling.
I think that is not related to anything.
var data = [
{
x: ['giraffes', 'orangutans', 'monkeys'],
y: [20, 14, 23],
type: 'bar',
selected: {
marker: {
opacity: 1,
},
},
unselected: {
marker: {
opacity: 0.2,
},
},
hoverinfo: "skip",
}
];
const config = {
responsive: true,
}
const layout = {
dragmode: "zoom",
clickmode: "select+event",
};
const plot = document.getElementById('myDiv');
Plotly.newPlot(plot, data, layout, config);
plot.on("plotly_click", (data) => {
alert(data);
});
plot.on("plotly_selected", (data) => {
alert(data); // NO events are captured on here~!
});

Research direction
Start with the linked CodePen reproduction and trace how the bar trace's hoverinfo: "skip" affects plotly_click and plotly_selected event handling. Inspect the relevant event and hoverinfo paths in plotly.js, then verify that both handlers still receive events when hoverinfo is skipped.
