This feels like an off-by-one error… when there’s an expand button towards the bottom of a file, the very last line is shown: <img width="951" alt="Screen Shot 2019-07-12 at 9 48 39 AM" src="https://user-images.githubusercontent.com/10070176/61144793-baec4800-a48a-11e9-8d4c-4b270dd2c54d.png"> In the screenshot above, I wouldn’t expect line 106 to be shown.
