[Translation] %parameters% are not replaced when file is first dumped as +intl-icuand then read #35328
Description
Symfony version(s) affected: 4.4
Description
We have a FileDumper that converts messages.en.yml to messages.en.php files. Since 4.4 this file became message+intl-icu.en.php with the same content.
Upon reading these +incl-icu.php files, the %placeholder% are no longer replaced with the correct value.
Spoke with @yceruto in #35264 (comment) and he suggested this is a different issue.
How to reproduce
See commits on https://github.com/ruudk/symfony-translation-bug-poc/commits/master
Possible Solution
The FileDumper should not just add +intl-icu to files.
