Redirecting a request behaves differently using onBeforeRequest listener than onHeadersReceived

Reported by benjamin...@gmail.com, Aug 14 
UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36

Steps to reproduce the problem:
1. Create an extension
2. Add an onBeforeRequest listener
3. Redirect every request to the request url

What is the expected behavior?
This should cause an infinite loop but does redirect the request only once.

What went wrong?
The request gets redirected only once. I can still surf the page. If I use the onHeadersReceived listener the redirection to the request url causes an infinit loop which causes the browser to throw an error. I expected this behaviour to be the same for the onBeforeRequest listener.

Did this work before? N/A 

Does this work in other browsers? N/A

benjaminfellner@ Thanks for the issue.

Tested this issue on Mac OS 10.13.3 and Windows 10 on the reported version 68.0.3440.106 by following the below steps.

1. launched Chrome and added the given extension in chrome://extensions.
2. Clicked on background.html and can observe many requests in Devtools -> Console in Windows, but on Mac OS can observe only two requests.
Attached are the screen shots of Windows and Mac behaviors.

Request you to check and confirm if this is the issue seen on Mac?

Thanks..

Thanks for the quick reply.
In my opinion the behaviour is the same for windows and mac.

It seems that there are more extension active on windows and therefore more requests. The requests on windows are also only redirected once (and not infinitely like for the onHeadersReceived listener). The log is sometimes summarized and sometimes there is another request in between and therefore its not easy to see that the request happens two times.
I highlighted some of those requests.
