`intl` date handler shows wrong language when default and user language is different in panel

[afbora]

intl date handler shows wrong language when default and user language is different in panel. I see all UI strings/variables as TR (user language is TR, EN default language) but intl date handler shows English.

For ex: following info output is 04 Nov, 2023, but it should be 04 Kas, 2023

type: pages
info: >
  {{ model.createdAt.toDate('dd MMM, YYYY') }}

App setup

config.file

<?php

return [
    'languages' => true,
    'languages.detect' => true,
    'panel' => [
        'language' => 'tr',
    ],
    'date' => [
        'handler' => 'intl'
    ],
];

Language

Multi-language enabled and default language is EN and locale en_US

User

Logged user language is Turkish.

So Panel user language is Turkish but you're editing English content or Turkish content?

[afbora]

Yes, panel user language TR and editing English content. All panel UI and language dropdown (fetching query from collections) options TR except date.

This sounds similar to https://github.com/getkirby/kirby/issues/5269.

Where there's no obvious answer if the Panel should request the backend passing the content language or the user language as current language.

In your example, I could also see people arguing the info text should match the current content language, not the UI language.
