android: clear_notification command not working when several notifications are shown

Phone model: Oppo Find X2 Pro (ColorOS 11) Xiaomi Mi 9 (MIUI 12.0.4)

Last working Home Assistant release (if known): None

Description of problem: I’m using an automation that notify user’s mobile apps that some windows are opened. When the window is closed, the notification is cleared on all the mobile apps. It works perfectly when a single window is opened and closed. But when two windows are opened, it creates two notifications, and when the windows are closed, only one notification is cleared, the second one remains on the phones until manually dismissed.

I made the automation below to reproduce the issue. One notification is created, and cleared after 5 seconds, then a second notification is created with a different tag, and then cleared after 5 seconds. Then the first notification is created again ; 5 seconds later the second notification is created ; 5 seconds later the first notification is successfully cleared, but 5 seconds later the second notification is not cleared as expected .
