Infinite loop entered when using folder->idle() with Gmail

[frecco]

Describe the bug When using $folder->idle() an infinite loop is entered. Happened to discover this since i had Xdebug enabled. It some times worked but when I started deleting mails and moving them around it stopped. Now this happens every time.

Used config No config besides login information.

"Code to Reproduce"

        $client->connect();
        $folder = $client->getFolderByName('INBOX');
        $folder->idle(fn($message) => $this->handleReply($message), $timeout = 1200, $auto_reconnect = false);;

Expected behavior Getting new mesages from INBOX.
