[FocusScope] Dialog resets focus when leaving & returning to browser tab/window

[tigranpetrossian]

Bug report

Current Behavior

Dialog resets focus to first focusable element when browser tab is blurred.

Expected behavior

Focus should be retained when leaving browser window/tab and returning to it.

Reproducible example

CodeSandbox

Suggested solution

This might be because of trapFocus re-initializing on document focus, but I'm not 100% sure:

Hi @tigranpetrossian, that behaviour should now be fixed in the latest published release.
