Steps to reproduce the problem:
1. Install  slightly changed chrome plugin from https://github.com/anna-lareni/chrome-extension-http-headers. I only changed a few lines https://github.com/anna-lareni/chrome-extension-http-headers/commit/9542c2d9d59ea5217b607600a9b338dc5334395b
2. Open http://moerner.com/tests/chrome-debug-api/
3. Start the plugin via the green button top right
4. Reload the website via shift + reload

What is the expected behavior?
An initiator for every request incl URL should be shown.

What went wrong?
http://moerner.com/tests/chrome-debug-api/ -> {"type":"other"}
http://b.aklamio.com/widget-integration.js?1481620862017 -> {"stack":{"callFrames":[{"columnNumber":31,"functionName":"","lineNumber":10,"scriptId":"44","url":"http://moerner.com/tests/chrome-debug-api/"},{"columnNumber":11,"functionName":"","lineNumber":11,"scriptId":"44","url":"http://moerner.com/tests/chrome-debug-api/"}]},"type":"script"}
https://www.aklamio.com/ovlbtntrk?url=http%3A%2F%2Fmoerner.com%2Ftests%2Fchrome-debug-api%2F&utm_medium=blank&r= -> {"stack":{"callFrames":[]},"type":"script"}

As you see in line 3, the callFrames array is empty. 

On the other hand if I use the developer tools an initiator-URL is shown (see screenshot)

Did this work before? N/A 

Does this work in other browsers? N/A
