System notifications for received chat messages while in that chat are not silenced

## Steps to reproduce
1. Open a chat
2. Write back and forth, receiving messages in that chat while having the same chat open (app in foreground)
3. System notifications for new messages of the open chat are still shown, instead of being hidden since the messages are already visible in the chat directly

### Expected behaviour
When you receive messages in a chat, and you have the chat open, the corresponding notifications should not appear.

### Actual behaviour
They do (see steps above).
I have noticed this behavior in ~50% of cases, not always but it's not even rare.
