In overview, windows from all workspaces are shown for the second display (when using "Workspaces span displays")

Bug Description

I have disabled workspaces on primary display only, and I have enabled workspaces to span displays, in tweak tool.

Now things mostly work how I expect. Windows are isolated to the workspace they are and I can move them between displays (monitors). The issue is if I go into an overview mode. Then, for the primary display, I see only windows from my current workspace. But for the secondary display, I see windows from all workspaces being shown in the overview mode.

I would expect that only the windows from the current workspace are shown also on the secondary display in the overview mode.

It seems this one is reporting the issue:

There are few patches, but it does not like fixed.

So I do not care so much about switcher than the behavior described:

Observed behavior: Actvities overview (got by pressing the logo key), however, handles the two monitors differently: for the primary monitor, it exposes only windows on the current workspace, but for the external monitor, it always shows all windows on all workspaces.

Expected behavior: when /desktop/gnome/shell/windows/workspaces_only_on_primary is false, both monitors should behave the same, and both should show only windows on the current workspace.

I can confirm the bug. However, the bug reported on gnome's bugzilla is very old. I've been using ubuntu gnome 16.04 for the last two years and everything worked fine. I've seen this bug for the first time trying out ubuntu 17.10, so I would conclude it's either related to ubuntu's customization of gnome, or to gnome versions >3.18

I can confirm it as well. Occurred after upgrade to 18.04 (X and Wayland), worked fine with 16.04 (on Gnome). Unfortunately this is a core feature to my workflow, is there a workaround?
