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.

Inizia riproducendo il problema nel riquadro GitHub Pull Request seguendo i passaggi elencati, quindi confronta Revert Selected Ranges con il workflow del diff di Source Control. Il payload non indica alcun file sorgente né alcun test; il lavoro è completato quando gli intervalli selezionati non producono più modifiche duplicate o posizionate casualmente, oppure quando il comportamento è chiaramente documentato come previsto.
