plotly_legenddoubleclick never fires if plotly_legendclick return false

[mmakrzem]

I would like to wire my own event handling when the legend is single clicked or double clicked.

I created the following demo: https://codepen.io/mmakrzem/pen/wvzdVaM

Notice that only the plotly_legendclick event triggers when I single or double click in the legend. The plotly_legenddoubleclick event never fires (because the plotly_legendclick is returning false).

If I double click I also wouldn't expect the plotly_legendclick event to fire.

There is a timer there that tries to debounce it, here: https://github.com/plotly/plotly.js/blob/master/src/components/legend/draw.js#L371

It seems the default should be 300ms (https://github.com/plotly/plotly.js/blob/master/src/plot_api/plot_config.js#L171), but you can try changing it through config.doubleClickDelay

I'm also experiencing this behavior (plotly_legenddoubleclick never fires if there's a custom handler for plotly_legendclick), and I don't think it's related to the double click delay, as I set that to 5 seconds and the problem persisted.
