Ah, so this is what I missed: use of a custom skeleton. I tested all
kinds of overlays, but forgot to test a custom skeleton.

So, it did not break for overlays, while it breaks for skeleton, but
that is not weird: the checks for the skeleton are strict, while they
are lax for the overlays. So, that's what causes the failure for you.

This is important information, that should have been given in the commit
log (maybe not so extensively, but still),

Thank you for the feedback! 👍

Regards,
Yann E. MORIN.
