Steps to reproduce the problem:
1. Go to http://oss.sheetjs.com/js-xlsx/ajax.html
2. Open the Sources tab
3. Open the file xlsx.js
4. Set a breakpoint on line 11384 (var zip, d = data, isfile = false, n;)
5. Reload the page

What is the expected behavior?
The data variable contains a large string of data, it should display this as truncated text

What went wrong?
The whole inspector + chrome hangs and has to be forcibly killed.
