Steps to reproduce the problem:
1. Load a site that dynamically loads scripts from URLs that contain a querystring
2. open the dev tools
3. perform an action that triggers the download of the script you want to debug
4. verify in the Network tab that the script was, in fact, downloaded
5. check the Sources tab.  The script isn't listed anywhere.

What is the expected behavior?
the scripts should show up in the Sources, even if they have querystrings appended

What went wrong?
the scripts aren't listed in the Sources tab.

Did this work before? N/A 

Chrome version: 58.0.3029.110  Channel: stable
OS Version: OS X 10.12.5

if you force debugging in the script by adding a `debugger` statement, the script is displayed in a tab within the Sources tab with a name like `VM130817`.
