In theory you're right. In practice, gnome-shell gives extensions free rein to do whatever they want, including painting over whatever they like. gnome-shell can't enforce anything.
It just sounds like a bug in the extensions so you need a newer version of the extension that properly supports gnome-shell 3.36. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1875038 Title: Lock screen not really functioning - Gnome Shell extensions visible and active even in lock screen Status in gnome-shell package in Ubuntu: Invalid Bug description: Lock screen should block access to computer until the screen is unlocked. But, although it was fixed either in extensions, or the lock screen itself in Ubuntu 19.10, it is now present again. I can remove shortcuts from Dash to Dock bar, I can run whatever app is there. In my view, this is a security flaw that in some cases can lead to jokes (removing) or even crashing the computer if really multiple windows of some app are started. And who knows what kind of apps are there. I did report it in the past, I also reported the bug in Gnome Bugzilla and the extension bug reporting app - they were bouncing from one to the other. At some point the bug disappeared. I think Ubuntu should fix this until something bad happens. See the attachment.
