带有`wp.i18n`的`wp_set_script_Translations`在简单插件中不返回已翻译的字符串

Short description:

我尝试翻译JS文件中的字符串。为了测试它，我决定创建一个简单的测试插件。我有PHP和JS字符串。翻译后的PHP字符串工作正常，JS字符串不工作。

Tools and environment:

Plugin PHP file content:

<?php

/*
 * Plugin Name: Test
 * Text Domain: test
 * Domain Path: /languages
 */

/**
 * Init all
 */
function run()
{
    wp_register_script(
        \'script\',
        plugins_url(\'script.js\', __FILE__),
        array(\'wp-i18n\'),
        false,
        true
    );
    wp_enqueue_script(\'script\');

    wp_set_script_translations(\'script\', \'test\',  dirname(plugin_basename(__FILE__)) . \'/languages/\');
    load_plugin_textdomain(\'test\', false, dirname(plugin_basename(__FILE__)) . \'/languages/\');
}
add_action(\'init\', \'run\');

/**
 * Register a custom menu page.
 */
function register_my_custom_menu_page()
{
    add_menu_page(
        \'Custom Menu Title\',
        __(\'Custom Menu\', \'test\'),
        \'manage_options\',
        \'my_custom\',
        \'callback\'
    );
}
add_action(\'admin_menu\', \'register_my_custom_menu_page\');

/**
 * Display a custom menu page
 */
function callback()
{
    esc_html_e(\'Admin Page\', \'test\'); ?>
    <h1 id="h1"></h1>
<?php }

Plugin JS file content:

const { __ } = wp.i18n;

alert(__(\'js-alert\', \'test\'));

console.log(__(\'js-log\', \'test\'));

div = document.getElementById(\'h1\');
div.innerHTML += __(\'js-html\', \'test\');

Procedure for creating translation files:

使用创建POT文件wp i18n make-pot . languages/test.potcp languages/test.pot languages/test-de_DE.pomsgstr 字符串输入test-de_DE.po添加行"Language: de_DE\\n" 到test-de_DE.pomsgfmt languages/test-de_DE.po -o languages/test-de_DE.mowp i18n make-json languages/test-de_DE.po --no-purge --pretty-printLanguage files structure after performing the steps above:

wp-content/plugins/test/languages/test-de_DE-9a9569e9d73f33740eada95275da7f30.json
wp-content/plugins/test/languages/test-de_DE.mo
wp-content/plugins/test/languages/test-de_DE.po
wp-content/plugins/test/languages/test.pot

The content of test-de_DE.po that was used to create the MO and JSON

msgstr "Test DE"

#: test.php:35
msgid "Custom Menu"
msgstr "Custom Menu DE"

#: test.php:48
msgid "Admin Page"
msgstr "Admin Page DE"

#: script.js:3
msgid "js-alert"
msgstr "js-alert-de"

#: script.js:5
msgid "js-log"
msgstr "js-log-de"

#: script.js:8
msgid "js-html"
msgstr "js-html-de"

Result on my test website:

Additional context:

wp_set_script_translations 退货true 一直以来load_plugin_textdomain 退货true 一直以来，我知道我可以wp_localize_script() 但我想完全用wp.i18n

Plugin files structure:

/test
  /languages
    test-de_DE-9a9569e9d73f33740eada95275da7f30.json
    test-de_DE.mo
