Close batch: mru successor · case 02
The tab workspace reports an incorrect mru successor.
Case contract
Close requested clean unpinned tabs atomically; retain dirty and pinned tabs, select most recent surviving tab and preserve surviving history.
Why this case matters
Offline tab/panel workspace behavior; no browser or desktop framework is emulated.
