Cannot read encrypted room messages after E2E password reset

Description:

If you get invited to a encrypted group before you entered your E2E password and then reset it, youll not be able to read the messages in this group.

Steps to reproduce:

Account: Worker [has his E2E password entered]
Account: Victim [doesnt, also he has forgotten his e2e password]
Account: Admin [selfexplanatory]

1. Create with [Worker] a private, encrypted group and invite [Victim]
2. Reset the e2e password of [Victim] with [Admin]

Expected behavior:

After the steps [Victim] can read any new messages in the encrypted group. [Victim] also can write messages.

Actual behavior:

[Victim] can not send messages (no feedback, enter in textbox just does not work) in the encrypted group.
[Victim] can't see new messages in this group, he only see the placehodler-stars (******).
If [Victim] opens the direct link to the room, he gets redirected to the default channel.

Friendly greets and thanks in advance,

Start with the server stack trace in packages/rocketchat:notifications/server/lib/Notifications.js and packages/rocketchat:streamer/server/server.js, then follow the client E2E handshake and room-key request. Reproduce the password-reset flow and verify that the affected user can read new messages and send messages in the encrypted group without being redirected.
