// Check that the formatted phone number contains exactly
// the same digits that have been input by the user.
// For example, when "0111523456789" is input for `AR` country,
// the extracted `this.nationalSignificantNumber` is "91123456789",
// which means that the national part of `this.digits` isn't simply equal to
// `this.nationalPrefix` + `this.nationalSignificantNumber`.
//
// Also, a `format` can add extra digits to the `this.nationalSignificantNumber`
// being formatted via `metadata[country].national_prefix_transform_rule`.
// For example, for `VI` country, it prepends `340` to the national number,
// and if this check hasn't been implemented, then there would be a bug
// when `340` "area coude" is "duplicated" during input for `VI` country:
// https://github.com/catamphetamine/libphonenumber-js/issues/318
//
// So, all these "gotchas" are filtered out.
//
// In the original Google's code, the comments say:
// "Check that we didn't remove nor add any extra digits when we matched
// this formatting pattern. This usually happens after we entered the last
// digit during AYTF. Eg: In case of MX, we swallow mobile token (1) when
// formatted but AYTF should retain all the number entered and not change
// in order to match a format (of same leading digits and length) display
// in that way."
// "If it's the same (i.e entered number and format is same), then it's
// safe to return this in formatted number as nothing is lost / added."
// Otherwise, don't use this format.
