Reproduction Steps

In an Angular project:

1. Display a very big json file 200.000+ lines
2. After all the data is loaded call this._instance.getAction('editor.foldLevel2').run();
3. Every object starting from line 168840 isn't folded

Actual (Problematic) Behavior

Not all objects are folded correctly.

Expected Behavior

All objects should fold correctly despite the length of the file.
