Comma in NumberInput not accepted with Firefox 74

[kiad]

What you were expecting:
I expected to be able to type a percentage like "65,34", with a comma

What happened instead:
Once I type the comma, the whole input is erased.

Steps to reproduce:
I have set-up a small example : https://codesandbox.io/s/frosty-allen-xm38z with a "progress" field in the post element.
The progress field follow the documentation example of parse/format : it comes as 0-1.0 from the API, but is displayed and typed as 0-100 (which I have been doing for months without any issues).

Other information:
I noticed this issue since Firefox 74.0. Works well on Safari or Chrome.

Environment

• React-admin version: 3.4.0
• Last version that did not exhibit the issue (if applicable):
• React version: 16.12.0
• Browser: Firefox 74.0

This is related to how Firefox manages input type number, because it better handles langs.

I updated the documentation to better handle this case, thanks for the issue

Thank you. I tried in the Codesansbox to add the parseFloat but it still does not all to add a comma, and not a point anymore (point works previously).

Firefox switches between a dot and a comma depending on the language defined on the HTML tag. (eg. a dot if lang="en" or a comma if lang="fr")

You can overwrite the input languages by passing the following prop:

<NumberInput source="progress" options={{ inputProps: { lang: "fr" } }} />

Thanks a lot, it works indeed (I've been reading this in the meantime).
