Weird encryption behaviour

[Fingadumbledore]

Steps to reproduce

I log out of all sessions. If another person writes me a message while I am logged out, when I log in and want to read this message, I get this error: ** Unable to decrypt: DecryptionError: The sender's device has not sent us the keys for this message. **
However, if the other person quotes the message after I log in again, I can read it without any problems.

Outcome

If a message has not been decrypted, it cannot be displayed logically, but if it is quoted, the content can still be read.
If you then export the chat history as a text file or JSON, the messages can also be displayed, but this is not possible with Html exports.

Quoting a message is sending a copy of the quoted text. Just like you would if quoting a text in an essay, nothing weird there. Receiving messages whilst all your sessions are logged out is impossible due to Perfect Forward Secrecy.
