1. Open three pages with logged-out modal. Paste credentials for the same user in each and start log in process in each card. Initially this was the way to reproduce the issue.
2. Open developer tools in one page and see that there are multiple sessions and encryption keys and each of them is suffixed with cookie id that exists in your MariaDB instance.
3. Send notification. Ensure that:
- it is correctly decrypted
- once it is received there is just one olm session in IndexedDB and it is the one that initially had largest cookie ID
