Critical issue in feature for capturing content of responses #13908
Description
Recently I saw very similar issues about weird behaviour with AJAX requests.
After a small investigation I've discovered that NetworkReplyProxy (and NetworkReplyTracker) are the real source of the problems.
The problem:
Wrapping all network requests has the real impact on how WebKit processses network requests (even inside the context of the WebPage!). For example, synchronous AJAX requests don't work. Unfortunately, I didn't dig deep inside into. But the problem is that Webkit waits forever for sync requests (or sometimes for async requests too), so they will be never completed.
Affected issues (still collecting them):

#13881
#13806 (not sure about this one)
#13805 (yes, memory usage is affected too)
#13788
#11195
Proposal solution: revert all commits with this feature (PR is ready, just give me a green light)
