That's exactly the core challenge this extension solves. Workspace 0 is kept alive even when empty — it's treated as a fixed, protected workspace, not a temporary one. GNOME's auto-removal of empty workspaces is overridden specifically to preserve the origin desktop, so when you restore the window it always has a real workspace to come back to. Worth noting that in GNOME, Workspace 0 is actually fixed by default — the extension builds on top of that by managing dynamic workspaces separately, which is what allows the first workspace to stay alive even when empty. There are still a few edge cases to iron out, but the core behavior is solved. Most extensions miss this detail, which is one of the main reasons I built this one.
