1. Get a giant review, such that files are not loaded automatically
2. Navigate to an interesting file and load it.
3. Copy the link in your address bar, it should indicate a place within the review/change to go to, like https://reviews.example.com/rMA98e75e05c56bc094b628b36fefc36efef209cc6e#3cfb784f
4. Now open another browser window and paste that link

The change will open to the right location, but the file is not loaded. Given that the location in the review is explicitly provided within the URL, it would make sense to load the referenced file, since the user is more than likely to immediately load it anyway.
