Description Alexey Proskuryakov 2020-04-15 09:55:56 PDT

[new Intl.DateTimeFormat("default").resolvedOptions().locale,
new Intl.DateTimeFormat().resolvedOptions().locale,
new Intl.DateTimeFormat().format(new Date()),
navigator.language]

Shipping Safari and STP 100:

["ru", "ru", "15.04.2020", "ru"]

STP 104:

["ru-RU", "ru-RU", "15.04.2020", "ru-ru"]

Chrome:

["ru", "ru", "15.04.2020", "ru-RU"]

I am not aware of any reasons to change shipping Safari behavior, and definitely not to be different from Chrome.

Here is my system configuration, which actually surprised me, but ru-RU isn't there for sure:

$ defaults read -g AppleLanguages
(
    "ru-US",
    "en-US",
    "zh-Hant-US",
    "ja-US",
    "ko-US",
    "vi-US",
    "de-US",
    "fr-US",
    "zh-Hans-US",
    hi
)
$ defaults read -g AppleLocale   
ru_US

This is fixed internally for newer STP.
