Steps to reproduce the problem:
1. Console log new Error().stack from within a file with a source map

What is the expected behavior?
The printed stack trace should be resolved against the source map.

What went wrong?
It is not resolved against the source map.

Did this work before? N/A 

Chrome version: 53.0.2763.0  Channel: dev
OS Version: OS X 10.11.4
Flash Version: Shockwave Flash 22.0 r0

This only happens when logging stack traces manually. This is quite common practice, e.g. console.error(error.stack);
