"Delete for Everyone" in Group Video Call Widget can cause chat to scroll up

### Steps to reproduce

In our group video call application, we have a widget for handling messages. We’ve noticed that when clicking the "Delete for Everyone" button, the message list sometimes unexpectedly scrolls up, causing users to miss the latest messages.

### Outcome

#### What happened instead?

### Tasks
```

No file, test, or entry point is named. Begin by reproducing the issue in the group video call widget and gather the missing browser, operating system, application version, and homeserver details; trace the message-list scroll behavior when selecting “Delete for Everyone.” Done means deleting a message no longer unexpectedly scrolls the chat away from the latest messages.
