Two notifications show up when you get pinged, rather than one like you would expect. (Element Nightly)

[ArrayBolt3]

Steps to reproduce

1. Ask for someone to ping you.
2. Minimize the Element Desktop window.
3. Wait for them to ping you.

Outcome

What did you expect?

A single notification should pop up.

What happened instead?

Two notifications pop up, one from the message coming into the room as usual, and one from being pinged. The two notifications are identical.

Note that I don't think this used to happen - I believe it happened just after the last update. (I might be wrong there, but I'm pretty sure this is a recent issue, at least.)

Thanks for reporting the issue @ArrayBolt3 Don't have a Lubuntu 23.04 but cannot reproduce on latest Ubuntu 22.04.1 LTS. Can you send a screenshot of your notification settings?

This might a Synapse issue - matrix-org/synapse#14539

@weeman1337 Screenshot of notification settings:

I notice it only happens in certain Matrix rooms - if I'm pinged in a Libera.Chat room, this doesn't seem to happen, but if I'm pinged in a room such as @lubuntu-devel:lubuntu.me, or a semi-private room I'm a part of, I get the doubled notifications. One time it was even four notifications all at once.

@t3chguy That Synapse issue matches my symptoms quite well. Additionally, I noticed when using Thunderbird's Matrix client connected to my lubuntu.me homeserver, messages sent in the #lubuntu-devel:lubuntu.me room appeared doubled. So I think it's very likely that this bug is an unintentional duplicate of the one you linked to.

Closing in favour of matrix-org/synapse#14539

The Matrix spec says push rules should be evaluated against all live events, nothing about client doing any de-duplication
