restyle makes it harder to hover on trace legend

[colinfang]

This is very weird, and it seems to only occur when legends is inside the main plot.

Without restyle, the cursor changes immediately when over on the legends.

However with restyle, it requires a bit of luck to get cursor correctly hover on the legends.

 Plotly.restyle(graphDiv, {visible: [false, false, true, true]});
 Plotly.restyle(graphDiv, {showlegend: [false, false, true, true]});
