Selecting Revert Selected Ranges in Github pull request plane seems weird

• Extension version:0.42.0
• VSCode Version: 1.67.2
• OS: m1 mac pro

Seems like clicking 'Revert Selected Ranges' in github pull request plane works unexpectedly.

Steps to Reproduce:

1. Check out my PR
2. Go to Github Pull Request plane
3. Select any file under 'CHANGES IN PULL REQUEST'; a diff view appears.
4. Drag some changes, right click, select
   Unstage Selected Ranges -> no-op. I think it is reasonable since we didn't stage anything. However, when we select
   Revert Selected Ranges -> The file is messed up; some changes are duplicated and randomly placed.

At first, I expected Revert Selected Ranges to revert selected changes of the current file to what it looked like before the PR, but it didn't work. Is the behavior intended, or am I missing something?

If that is intended or not designed to use like this, is there a way to easily revert-some-selected-range-from-this-PR while staying on the 'diff' view? As a workaround, I manually git reset each file, revert the ranges that I don't want (in the diff view given by 'Source Control'), and re-stage the file.

Commencez par reproduire le problème dans le volet GitHub Pull Request en suivant les étapes indiquées, puis comparez Revert Selected Ranges avec le workflow de diff de Source Control. Le payload ne nomme aucun fichier source ni aucun test ; le travail est terminé lorsque les plages sélectionnées ne produisent plus de modifications dupliquées ou placées aléatoirement, ou lorsque le comportement est clairement documenté comme étant intentionnel.
