• Laravel Version: 8.50.0
• PHP Version: 8.0.8

Summary:

When using Model::on(...)->first() PHPStorm doesn't know the real type of the returned instance.

// PHPStorm know that the returned instance is `User|Builder|Model`
$user1 = User::first();
// PHPStorm know that the returned instance is `Builder|Model` but not `User`
$user2 = User::on('read_replica')->first();
