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.

Bắt đầu bằng cách tái hiện vấn đề trong ngăn GitHub Pull Request theo các bước được liệt kê, sau đó so sánh Revert Selected Ranges với quy trình diff của Source Control. Payload không nêu tệp nguồn hay bài kiểm thử nào; được xem là hoàn tất khi các phạm vi được chọn không còn tạo ra các thay đổi bị trùng lặp hoặc được đặt ngẫu nhiên, hoặc khi hành vi này được ghi lại rõ ràng là có chủ đích.
