Bug: The date field in the scheduled publication window does not allow you to edit the date in a field with languages other than English

[Molju]

Describe the Bug

Hello, I ran into a problem that if the language is set to a language other than English, the date field in the publication planning window does not allow changing the date in the text of the field itself, for example: change seconds, year, etc. After leaving the field, it returns the date to the date selected through the picker. Everything works fine for English. For languages I have tested (Russian, Chinese), the date returns to the selected one.

I would also like to ask you to add date formatting to the schedulePublish configuration, not just time, as is done for the date field in collections.

payload.config.ts

// storage-adapter-import-placeholder
import { sqliteAdapter } from '@payloadcms/db-sqlite'
import { payloadCloudPlugin } from '@payloadcms/payload-cloud'
import { lexicalEditor } from '@payloadcms/richtext-lexical'
import path from 'path'
import { buildConfig } from 'payload'
import { fileURLToPath } from 'url'
import sharp from 'sharp'

import { Users } from './collections/Users'
import { Media } from './collections/Media'
import {Categories} from '@/collections/Categories'

import { ru } from '@payloadcms/translations/languages/ru'

const filename = fileURLToPath(import.meta.url)
const dirname = path.dirname(filename)

export default buildConfig({
  i18n: {
    fallbackLanguage: 'en',
    supportedLanguages: { ru },
  },
  admin: {
    user: Users.slug,
    importMap: {
      baseDir: path.resolve(dirname),
    },
  },
  collections: [Users, Media, Categories],
  editor: lexicalEditor(),
  secret: process.env.PAYLOAD_SECRET || '',
  typescript: {
    outputFile: path.resolve(dirname, 'payload-types.ts'),
  },
  db: sqliteAdapter({
    client: {
      url: process.env.DATABASE_URI || '',
    },
  }),
  sharp,
  plugins: [
    payloadCloudPlugin(),
    // storage-adapter-placeholder
  ],
})

Russian language behaviour:

2025-07-18.23.27.17.mov

English (default) language behaviour:

2025-07-18.23.28.05.mov
