Undo Close All needs to be fixed

[DivergentEuropeans]

'Undo close all' was disabled recently because it was broken. But the code was just commented out and should be investigated to re-enable this feature where if you close all your tabs, you can undo that close.

@1000TurquoisePogs can you assign this to me??

@DivergentEuropeans ?

Hey @anj20 sure! But before you jump into it, do you have the App server enviornment set up successfully, with the ZSS mock server?

Or do you have access to z/OS (if not using ZSS mock server?)
