Steps to Reproduce:

1. Create a PR including a change that's a file deletion
2. Open diff view from the tree

In the "GitHub Pull Requests" tree, the view for the file shows a commentable range on the right hand side for the new empty file. Trying to add a comment there fails. If checked out, the "Changes in Pull Request" tree, both sides are not commentable. Commenting should be supported on the deleted file
