Set content_classes and block permissions

I found this little bug (may be isnt a bug).

In page.html.twig file there is the option to change the content to .col-sm-12 class and desapear sidebars with .col-sm-3 class if there is not block inside it.

But if you let a block like Tools, the Sidebar dont disappear even if the block is not visible by a anonymous user.
You see a empty sidebar with .col-sm-3 class.

If you go to edit block permissions and add visibility to admin and authenticate users, everything work again and sidebar disappear.

May be the theme Will need a more specific way to apply classes in set content_classes?
