Steps to reproduce:

1. Open the CodePen example
2. Use tab-key navigation to move focus to the first ARIA listitem of the ARIA list representing the list of messages
3. Observe NVDA automatically toggles focus mode on when the ARIA listitem is focused (this is thanks to the fix for issue 13357)
4. Press tab to move focus to the button representing the message sender
5. Observe NVDA does not toggle browse mode on despite the button being contained within an element with role="document"
6. Press tab once more to move focus to the anchor element representing the time
7. Observe NVDA toggles browse mode on when the anchor is focused

Actual behavior:

NVDA does not toggle browse mode on when focus is moved to a button contained within an element with role="document"

Expected behavior:

NVDA should toggle browse mode on when focus is moved to a button (or any element) contained within an element with role="document"
