https://ui.nuxt.com/docs/components/toast

On the official Toast demo page:

1. Open a toast (e.g. the first one on the page: Add to calendar).
2. Obvseve how the progress bar is elapsing.
3. Manually close the toast with the X close button, before the progress bar elapses.
   (The same issue also occurs, when clicking an action button in the toast.)
4. Open another toast.
5. Observe how there is no progress bar and how the toast does not automatically close,
6. Hover over the toast or switch browser tabs to re-trigger the progress bar and auto-close behavior.

Description

New toasts no longer automatically close (elapsing progress bar is missing), when a previous toast was manually closed or its actions were interacted with, until the browser tab is switched or the new toast is hovered.

Additional context

No response

Logs

Start with the Toast component and the official Toast demo page linked in the reproduction steps. Reproduce the sequence of manually closing or interacting with one toast before opening another, then trace the expiration and progress behavior. Done means a new toast resumes its progress bar and automatically closes without requiring hover or a browser-tab switch.
