There is actually no view-state preserved for untitled files because we never had untitled files surviving a restart.
I wanna check if this is low hanging for November, otherwise I will push it out.
Will do in January, it is just a matter of persisting our untitled view state that we already track in https://github.com/Microsoft/vscode/blob/master/src/vs/workbench/browser/parts/editor/stringEditor.ts#L36
Preserve view state for untitled files between restarts (fixes #16588)
The view state of untitled editors should now preserve and restore after restart with hot exit enabled. This currently only works when having a folder opened. For empty workspaces we still need to tackle #207
