Desktop notification isn't closed after message is read in app (on Gnome)

### Steps to reproduce

1. I receive a new message and a desktop notification is displayed
2. I open the app via the dock icon (not via the notification)
3. I read the message

### Outcome

#### What did you expect?
I'd expect that the app tracks the relation between message a notification and withdraws/closes the notification related to the message once the message is read. (Apparently, Gnome uses the Freedesktop Notifications specification, which supports closing notifications.)

#### What happened instead?
The desktop notification persists. Desktop notifications accumulate over time and the unread message count badge at the dock icon shows a false indication for unread messages.

### Operating system

Ubuntu 25.04 / Gnome

### Application version

Element version: 1.11.101

### How did you install the app?

via apt package manager

### Homeserver

_No response_

### Will you send logs?

No
