7.2.6

Description

If you fetch messages using MessageCatalogue::all() from a MessageCatalogue, it automatically merges domain and domain+intl-icu messages. However, MessageCatalogue::getMetadata does NOT do this, causing messages to exist but metadata missing.

This gets more serious as ->getDomains() returns the plain domains (without +intl-icu), causing metadata being dropped in most things that loops over messages (such as \Symfony\Component\Translation\Bridge\Crowdin\CrowdinProvider)

How to reproduce

<?php
require_once './vendor/autoload.php';

$catalog = new \Symfony\Component\Translation\MessageCatalogue("en");
$catalog->add(["key" => "The text"], domain: "messages+intl-icu");

$catalog->setMetadata("key", ['notes' => [['content' => "This will disappear"]]], domain: "messages+intl-icu");

foreach ($catalog->getDomains() as $domain) {
    foreach ($catalog->all($domain) as $key => $value) {
        // Shouldn't be null here!
        if($catalog->getMetadata($key, $domain) == null) {
            echo "Woe and despair, my metadata is hiding from me!\n";
        }
    }
}
