Bug Description

Starting from PHP 8.4 it's possible to call new ReflectionGenerator($generator) on a closed generator (before 8.4 it throws a ReflectionException which is what Tracy relies on in BlueScreen::findGeneratorsAndFibers). This leads to an unexpected ReflectionException in section-stack-generator.phtml ($ref->getTrace(): it fails if the generator is closed).

Here is an example of the changed behavior.

Steps To Reproduce

Run the following code with PHP 8.4:

$generator = (function (): iterable {
    yield 5;
    throw new \Exception(sprintf('%f', microtime(true)));
})();
$fn = function ($generator)  {
    foreach ($generator as $value) {
    }
};

try {
    $fn($generator);
} catch (Exception $e) {
    echo "exception\n";
    $file = sys_get_temp_dir() . '/' . uniqid('bluescreen_');
    \Tracy\Debugger::getBlueScreen()->renderToFile($e, $file);
}

echo "OK\n";

Expected Behavior

Closed generators should be excluded the same way as they were before PHP 8.4.

Possible Solution

Check ReflectionGenerator::isClosed in findGeneratorsAndFibers.
