Disabling Unite extension should bring back control buttons of GTK+ 3 application

Steps to reproduce

1. Install Unite extension from http://extensions.gnome.org/
2. Disable Unite extension via http://extensions.gnome.org/local or Tweaks
3. Open Nautilus (or any application that has a big Header Bar)
4. Maximize the window

Expected behavior

Control buttons (minimize, maximize, close) should appear in Nautilus's Header Bar

Current behavior

Control buttons are still missing despite Unite being disabled

Workaround

Remove the extension

I just encountered the EXACT SAME issue with gnome-shell 3.28 on fedora28.

I was installing bunch of extensions, and while playing found some of windows' control buttons gone. It costs some time to figure it out, and it's really annoying...

Unite uses CSS to hide window buttons on HeaderBars and window decorations on Wayland.

When CSS is added/removed to the GTK theme all applications should be restarted for the changes to take effect.

Applications like nautilus run on the background when you close them, so you should use killall nautilus.

I'm closing this since it is not a bug of this extension. If this is considered a bug, the it is a GTK+ bug.

@jonian If what you said is true, in theory, removing the extension should not be different from merely disabling it.

I tested this not just with Nautilus, but also GNOME Monitor and Tilix. These apps don't run on background when you close them.

@KSXGitHub looks like CSS was not removed properly in the latest version. It is fixed now in master branch. Thank you for your help.
