Steps to reproduce the problem:
1. click pretty print on js minified file 
2. enter a break point
3. push play to the breakpoint and it stops on the minified version, impossible to debug that way

What is the expected behavior?
breakpoint stops on pretty print format 

What went wrong?
I don't know. It doesn't happen with regular chrome, but in canary it does.

Did this work before? Yes Regular chrome (not canary)
