Perhaps I'm missing something, but synthetics gives you no indication which items did not return at the moment a script times out.
The waterfall only lists successful or error-ed responses within the timeout window.
How do you know which requests from the page did not return within the timeout window?
I am dumbfounded as to why we can't know what was in-flight and did NOT return at the time the timeout was reached. Without that information how do we know what was slow?
