Diff is only working for commited changes not 'File Saved'

First of all, I love your extensions. Thank you so much for this work.
I am not super at ease with visual studio but what I like to do is:

• Modify the workflow in the workflow editor of usegalaxy.org
• Download the workflow
• Inspect the changes before commiting
  It seems that I cannot do that. I tried:
  
  Also, I don't know if it is possible to include that in the source control. This would be amazing.

Thank you!
Ohh I see, the File Saved History feature in the Timeline was introduced in VSCode after I added the workflow clean compare feature so it is not supported right now. It is probably just trying to find a git reference that doesn't really exist.

I'll have a look and see if I can make it work! Thanks for the report!

For info, it raises an error with files which are 'added' not commited:

I was investigating this recently because now (also) real commits in the timeline cannot be processed for comparison. I found out that the VSCode internal API changed and we can no longer access the necessary information from the timeline. So we will need to wait for a solution in microsoft/vscode#177319 for this to work... 😞
