Erases content when using 7 MB file

[lemairecarl]

I just used your package on a >7 MB JSON file. After working for 30 seconds, it just erases the content of the view.

Here's the file:
fqsp.json.zip

It's been produced with python's json module. Maybe there's weird shit in the file, but I don't think python would do that to me.

Maybe it is the same issue. Here is a dataset from https://restcountries.com/v3.1/all , that lead to an empty file when re-indenting:
restcountries.json

Same here, independently from file size, calling reindenting clears the whole file.
