"Modern" Pages "Pages" navigation node behaviour

Currently we experience some issues with the "Pages" Quick Launch navigation node on modern UI pages: After a user removes the "Pages" node from the navigation using the control below the left hand navigation, Pages is still visible after a page refresh on modern UI Pages. In "classic" elements and "modern" lists and libraries, the "Pages" node is not visible. Reproducible on different tenants. 

I have in mind there was a blog post from Microsoft announcing the "Pages" node with the remark, customers are anytime able to remove the node, but I cannot find the post. Is there anything I've missed?
