S3 because an NVDA user is unlikely to do this and regardless can work around this by manually switching to focus mode.

NVDA doesn't switch to focus mode here because the crop area doesn't have an interactive role. I might have suggested role="separator", but NVDA doesn't support interactive separators yet. role="slider" is probably the next best fit, albeit not great, but perhaps still better than no role.
