If you have a parent page and a child page and the parent page is restricted,
then the child page will (correctly) be likewise restricted. But if you MOVE
the child page somewhere else, it stays restricted even though its new parent
has no restrictions.

I was able to correct the situation by adding and then removing the same
restriction from the new parent page, which had the effect of clearing out
the child restrictions as well.

I cloned this issue because the error still exists in 2.9.0 and the original issue has been marked as closed
