DK 8.7 face tagging: confirm will trigger a new face scan?

[Carol C. Kankelborg]

This is a new setting in 8.7. I came across it about a month ago. See the snippet from a conversation about it in this group. The documentation is now up-to-date, but it can take a veteran user by surprise.

Hi all,

The option is now documented in the online handbook:

Best regards

The tool tip says "Set this option to automatically start a new background face recognition scan when a new face is tagged."  I don't see that item documented at https://docs.digikam.org/en/setup_application/miscs_settings.html#scan-operations but it does appear in that screenshot.
