window management - if a window is always on top, it will always get focus after switching between workspaces

Imagine I have an small terminal window open all the time for doing quick arithmetics. I have set it to be always on top since I need to constantly see it. I have also some other windows open (other terminals, nautilus etc.) on which I am really working and they have the window focus most of the time.

What happens:
Whenever I switch to another workspace and come back to the current workspace, I see the 'always on top' window gets the focus, even if I left that workspace when another window had the focus.

What should happen:
When some window has the focus in any workspace, it should keep the focus. By switching to a new workspace, focus of the windows of the old workspace should not change.

How to reproduce the bug:
Open several windows in a workspace. Make one of the windows 'always on top' from its window accessibility menu (Window 1). Then click on some other window to give it focus (Window 2). Now go to another workspace (by pressing Ctrl+Alt+Left/Right) and then come back. You will see that Window 1 has the focus, instead of Window 2.
