Steps to QA

Note, the core team are the only ones that can test this as they have the feature flag for StarSearch for Workspaces.

1. Go to /star-search
2. Ask a question.
3. Only the chat area scrolls and not the body.
4. Go to a workspace on a medium or larger screen size.
5. Shrink the browser window so that the content can be scrolled.
6. Notice the scroll bar for the body and it's scrollable.
7. Open StarSearch.
8. Ask a question.
9. The body remains scrollable, but notice in the StarSearch embed that only the chat area is scrollable.
