### Description

The following code:

```php
<?php

set_error_handler(function() { throw new \Error(); });

function &gen() {
    try {
        yield 1;
    } catch (Error $e) {
        print "Caught";
    }
}

foreach (gen() as $y);
```

Resulted in Uncaught Error

But I expected this output instead:
```
Caught
```

I wouldn't change the longstanding behaviour in current PHP versions, but should be fixed for
PHP 8.2 possibly, for academical correctness at least.

### PHP Version
