"This message is not decrypted yet" instead of message

[andi-makes]

Describe the bug

While having a channel open, the most recent received message will sometimes show as "This message is not decrypted yet", see screenshot.

After receiving another message, the previous message will show correctly, but the newest message might maybe show as "This message is not decrypted yet".

Reproduction

The most reliable way I've found to reproduce is:

1. Have two Cinny clients open side by side, logged in with the same user
2. Send a message on one client
3. The other client (most of the time) will show the "This message is not decrypted yet" message

A less complicated way to reproduce is to have someone message you, but that doesn't seem to be causing the issue every time.

Expected behavior

To show the message instead of "This message is not decrypted yet"

Platform and versions

1. OS: Linux
2. Browser: Firefox 135.0
3. Cinny version: 4.3.0 (web browser)
4. Matrix homeserver: self-hosted dendrite v0.14.1

Additional context

A workaround is to switch to a different channel and back again, then the message shows correctly.

I've also tested a PR of a friend after talking to them about this issue a little bit, and it seems to fix this issue: #1992

As per my testing, I feel like this fixed it #2209. Feel free to test.

I can confirm that the "This message is not decrypted yet" message is being replaced with the decrypted message very quickly when using the PR-version of cinny. The PR fixes the issue for me.

Thank you for your quick work!
