Nature of issue?

Details about the bug:

When I upload a JSON file that's sufficiently long (I'm not sure what the limit is), the file will appear empty when I navigate to it via the sidebar. I can even go into the file and start writing more json and it doesn't interfere with the original invisible json. I'm not sure if it's limited to JSON or not. I think one of my students tried this with a CSV file and saw something similar but I haven't tested again to confirm.

This only happens if I upload the whole file. If I create an empty json file, and paste in my text there's no issue.
