Toaster notification persists and doesn't disappear

[btseee]

I'm on Windows using Firefox 144.0.2 (64-bit).
The toaster notification sometimes fails to disappear after being triggered. This issue has been present across multiple versions.

When navigating to another page, the toaster element remains in the DOM and continues to display.

Steps to reproduce:

• Trigger a toaster (e.g., by clicking a button).
• Navigate to a different page.
• Observe that the toaster remains visible and still exists in the DOM.

Expected behavior:
The toaster should automatically disappear after its timeout or be removed when navigating away from the page.

Actual behavior:
The toaster remains visible and persists in the DOM even after page navigation.

First page, it appeared from a button :

Second page, it appeared on top left side of the screen:
