STPPaymentCardTextField postal code entry issue in Russian locale

[lauri-koli]

Summary

The STPPaymentCardTextField postal code entry behaves erroneously when the app is set to Russian language. After entering the CVC focus moves to the postal postal code field but the field is out of bounds of the STPPaymentCardTextField. The issue does not appear when using short placeholder for CVC field instead of the default.

Here's a link to a video which shows the incorrect behaviour.

Code to reproduce

A STPPaymentCardTextField with default configuration except having postal code entry enabled.

let field = STPPaymentCardTextField()
field.postalCodeEntryEnabled = true
...

iOS version

Tested iOS 13.5.x.

Installation method
