Is canEdit needed here? The useEffect above seems to set isOverlayActive back to true even if it becomes false here. Or is this check meant to prevent this tiny blip of isOverLayActive being set to false and then right away to true?

Correct. It's not always noticeable, but there's also no need to attach an event callback when editing is disabled.
