Plot.ly sankey layout.separators not work

Hi,
I need to show float number in sankey chart using comma (,) as decimal separator and dot (.) as thousand separator, but the user can customize this option.
I found the layout.separators option that works for other types of charts, but in sankey it doesn’t work,
I’m wondering if I’m missing somethings or this option isn’t available or it is a bug for sankey charts.

Here a dumb example.

Thanks in advance for reply :wink:

That looks like a bug to me. Would you mind opening a new report on https://github.com/plotly/plotly.js/issues/new
