Checking behaviour of useNationalFormatForDefaultCountryValue=true

[4jandals]

The behaviour of useNationalFormatForDefaultCountryValue=true as described in the docs suggests that when a number matches the defaultCountry the number will be formatted as a national number. This doesn't seem to be happening for me.

i.e. I have this basic definition

<PhoneInput 
  defaultCountry="GB"
  value={field.value}
  onChange={field.onChange}
/>

And then I enter a number as 01234 100100 which is stored in the database correctly as +441234100100, when the form is re-rendered, the number becomes +44 1234 100100. Where as I'm expecting it to be 01234 100100 since it's a GB number which matches the defaultCountry.

Or am I misunderstanding the behaviour here? Basically if a user enters a number for their country, I'd like to show the national format. Whereas if a user enters a number for a different country, I'd like to show the international format.

That behavior works only on the /input sub-package.

If that's not the issue then you could post a link to a minimal sandbox showcasing the supposed issue.
