I can use PHP in custom JS/CSS. Is it designed?

Thank you for your great plugin!

By chance, I found out that I can use php code in custom JS/CSS. Is it designed?
If it’s not designed, hope it’ll be fixed soon.

Sample PHP which I’ve tested.

<?php
echo "console.log('php echo');";
?>

<?php
echo "body{background:red;}";
?>

PS
I found this topic.
