Steps to reproduce the problem:
I build a extension which uses WebRequest-API and Debugger. I want to connect the Request Data from both APIs, but the frameId / requestId doesn't match.

At WebRequest the requestId is a string with format "01234". At Debugger the requestId is a string with the format "54321.123".

Nearly the same issue exists with the frameId. At WebRequest the frameId is a number with format 1234. At Debugger the frameId is a string with the format "54321.123".

How can these data matched? What is the best way?

What is the expected behavior?

What went wrong?
Type doesn't match.

Did this work before? N/A 

Does this work in other browsers? Yes
