Changing locale does not update mode bar buttons labels

[fhurta]

I created pen initially in German - the buttons titles and dates on X-axis appears in German. Then changed the locale to English. The date format on X-axis updated but the buttons still contain the German texts.

Hmm. I think I got it to work: https://codepen.io/etpinard/pen/RMKmoZ

Does it work for you? I tried in Chrome and Firefox (current versions) now and it still does not work.
The names on X-axis are updated but hovering over buttons, I still see german titles (e.g. Lassoauswahl for Lasso selection).

Ha, now I see it. Thanks!

Plotly.plot should not be used on a plot with existing data - its behavior is weird: it adds the new data to the existing traces and ignores layout. I guess it does update config but this method should be considered deprecated.

If you meant to not change the plot, Plotly.newPlot does work as expected. Plotly.react however, which is really the only other approved way to change config, does not work correctly - it shows the same behavior as Plotly.plot - so I'll take that as the item to fix here.
