Minimal PHP Code Causing Issue

See https://getrector.org/demo/1ec2fda5-2490-6c56-9d12-93cf2aafeb8a

When there's a throw new Exception in the match, like here:

<?php

final class DemoFile
{
    public function run($param)
    {
        return match ($param) {
            'a' => 'hi',
            'b' => 'bye',
            default => throw new Exception('no salutation'),
        };
    }
}

The downgraded switch should not add a return to throw new Exception

Expected Behavior

public function run($param)
{
    switch ($param) {
        case 'a':
            return 'hi';
        case 'b':
            return 'bye';
        default:
-            return throw new Exception('no salutation');
+            throw new Exception('no salutation');
    }
}
