Calls adds +1 to the number of the tel URL or to the number of the contact when the number does not have a country code

If I have a contact with number 0800123456 and I click 'Call', Calls will dial +10800123456. If I have a contact with number 455 and I click 'Call', Calls will dial +1455. I'm from Ukraine, but even if I change my locale from US to Ukraine, +380800123456 and +38455 won't be valid numbers. They must be without country codes.

I propose to make Calls not add the country code when the tel URL does not have it because it causes problems and it is wrong. Usually most contacts have the country code. Even if users have some contact without the country code and they are abroad, they will be able to edit the number of the contact right before dialing, save it and dial.
