Description

For some reason diff editors are not added to the history when navigating. When doing some digging in this it seems DiffEditors get disposed of when closing the editor (unlike normal single file editors). You can see the group tries to re-open them but falls into the return when they're already disposed, so nothing happens.

Why is this important? In GitHub when reviewing code you can open a file fully in isolation then click back to the diff. In VSCode this isn’t easy to do.

Steps to Reproduce:

2. Now navigate to another file
3. press back
4. VSCode is unable to get back to the diff editor

Source Control

1. Make a change then go to source control and click the diff
2. Close the tab then click back
3. VSCode is unable to get back to the diff editor
