I wasn't able to undo the deleted file, the console reported this 404:

https://github.com/sindresorhus/refined-github/new/linkify-code?filename=source/features/format-conversation-titles.tsx

This is probably because that 404 URL should be this instead:

- https://github.com/sindresorhus/refined-github/new/linkify-code?filename=source/features/format-conversation-titles.tsx
+ https://github.com/kidonng/refined-github/new/linkify-code?filename=source/features/format-conversation-titles.tsx
