Overlay enforcing focus not returning focus to the last focused element in the overlay

Environment

• Package version(s): 8.5.5
• Operating System: macOS Ventura 13.1 (22C65)
• Browser name and version: Version 109.0.5414.87 (Official Build) (arm64)

Code Sandbox

Steps to reproduce

1. Start typing in the overlay's input box.
2. Wait 2 seconds.
3. Notice how the focus is not returned to the input box but instead to the overlay's root element.

Expected behavior

I'd expect the focus to be returned to the last focused element in the overlay. Otherwise, it's particularly problematic for omnibars.
