Closing expanded view with [x] stays in "Expand" tab

[zengin]

Describe the bug
Dismissing expanded view does not retain tab selection.

To Reproduce

• Go to Graph Explorer
• Run a query that has a response body (GET /me should work in sandbox)
• Click on "Expand"
• Dismiss the expanded view by clicking on [x]
• Response pane stays with a focus on Expand "tab" without any content being shown as if there is no response.

Expected behavior
I think whichever tab is chosen in the expanded view should stay selected when the expanded view is dismissed.

A nice-to-have would be to always remember the selected tab, e.g. expanding "code snippets" tab defaults into "response preview" being selected in the expanded view.
