Ionic Framework Version

v8.x

Current Behavior

We are currently migrating to Ionic 8.4.1 from Ionic 7 with Angular 18.2.

Now we are facing following issue with ion-toast:
When an ion-toast will be present the css class "backdrop-no-scroll" is added to the body. And the class will be removed from body after the toast dismiss. This was the behaviour with Ionic 7 and with Ionic 8. But with Ionic 8.4.1 the class stay there and is not removed from body after the toast dismiss.

For me this seems to be a bug and I am able to reproduce this very easy. With the following code you can reproduce the issue. Just take a look at the HTML (body in iframe). After you change the ionic version to 8.4.1 in the package.json and reload the code you see the difference.

In case this is a new feature or I did something wrong, maybe someone can tell me how to remove this class on my one. :)

Expected Behavior

The "backdrop-no-scroll" css class is removed from body when toast dismiss.

3. Go to package.json and set ionic version to 8.4.1 - wait for loading dependencies
4. Reload the page and take a look at the body tag (in the iframe) again.
