hovertemplate d3-format numbers ignoring locale

[jwmann]

When I set the locale, the dates are formatted correctly. But the numbers using the d3-format ignores that locale and instead follows the en-us default format and not the defined format from Plotly.

As per the built-in locales. => https://github.com/plotly/plotly.js/blob/master/lib/locales/fr.js#L86-L87
For FR, the separator should be a space " " and the decimal should be a comma ",".

Here is a sandbox of my implementation.

Hover over the bars on the chart.

The $000,000.00 should look like this $000 000,00 in FR

Maybe I'm missing something obvious though.

Thank you @jwmann for reporting this issue. I don't think you're missing anything obvious: the problem probably lies in our current implementation of hovertemplate. We will work on a fix as soon as possible.

Thanks again :)
