[FIX] survey: resolved the popover issue stuck in a live session

Before this commit:
In the survey, when you start a live session and click on the URL the `copied`
popover appears but doesn't go away.

After this commit:
Now that popover will close automatically.

Reason:
There was already a `tooltip` instance on the element and we try to add the
`popover` on that element which causes an issue.
