chore: Attaches tooltip classes to popover container

[pan-kot]

Description

The tooltip test classes were attached to the div that contains a popover container. However, when the container becomes hidden due to scroll logic, the outer div stays and gives a false positive when checked with isDisplayed if using webdriverio v9. In the PR the classes are moved to the popover container so that the tests produce expected results.

How has this been tested?

See a failed dry-run: https://github.com/cloudscape-design/browser-test-tools/actions/runs/12945599198/job/36179765443?pr=109

The tests succeed with the fix applied: #3218

Why is styles.root staying here? it is also a test-util only style, what is the use-case of selecting it, if it is incorrectly placed in the DOM?

Why does this DOM node needed in the first place?

---

There is an avatar test util pointing on this DOM node too: https://github.com/cloudscape-design/chat-components/blob/81f675f568a82891661839f382262b80ea276289/src/test-utils/dom/avatar/index.ts#L14

Do you plan updating it in a separate PR?

[pan-kot]

That's a good call out. I will create follow-up PRs that will 1) Remove the dependency on the tooltip wrapper from Avatar and 2) Remove the root style from this node.

I will also check if there is an opportunity to remove the node altogether. I think the "contentAttributes" and the testid can be passed down to the internal container.
