Don't expand parent element if it's the root in single folder workspace when editing an element in explorer.

Fixes #72626

This trully fixes that issue.
However I have left some comments in your changes. Can you please address them.
Also why does this fix this issue? How did you find that this is the root cause?

[jeanp413]

@isidorn Looking at this in more detail I found that the real problem is when disposing the input element because the renderElement method gets sometimes called more than once between this.tree.expand(e.parent!), this.refresh(false, e.parent); and this.tree.reveal(e);, and the ignoreDisposeAndBlur flag is still turned on because of the 100ms timeout. I'll update my PR with a better fix.

[jeanp413]

This seems to be working except that it breaks when you are editing an element and click on the Refresh or Collapse All buttons, maybe they should be disabled like the New File and New Folder buttons.
Also I think ignoreDisposeAndBlur flag is no longer needed.

[isidorn]

This is good work. Let's merge it in. I will remove the ignoreDisposeAndBlur and check the refresh action. Thanks a lot!

[jeanp413]

Great! Don't forget about the Collapse All action, it should also be disabled while editing.

[isidorn]

Collapse All does not break anything for me. So I left it enabled.

@isidorn I just build and tested it from source code, is this expected?

[isidorn]

You are correct. I have tackled that via 0991cb5
Thanks!
