iPhone decimal keyboard does not always match with the decimal separator used in number input.

Steps to repro:
- have <input type="number" inputmode="decimal" value="1.99">
- have iPhone region set to location that uses comma as decimal separator (for example Estonia)
- have iPhone number format set to 1,234,567.89
- open the page in Safari. Safari displays the input as "1,99".
- try to edit the field -- Decimal keyboard has "." instead of ",".

The best expected result:
- input should honor the locale defined by <html lang> and display the input values and keyboard accordingly. So in case on <html lang="en-US> the input displays "1.99" and keyboard has "." and in case of <html lang="et">, the input displays "1,99" and keyboard has ",".

Minimum expected result:
- Both input and keyboard match with eatch other (preferably using the number format chosen in iPhone settings).
