Safari autofill international phone number

Hello!

Safari Autofill keeps removing the "+" sign from my phone number. I'm located in Moscow, Russia and whenever I order something the phone should be provided in international format , i.e +7 and so on.

This is exactly how the phone is filled in my contact card and when I click on autofill it also shows a plus sign, but when I click to fill it is removed. It is very annoying to add it manually each time and it makes autofill useless.

Is there a way to fix this please?

P.S: Chrome browser is doing it correctly
