My question was, why *synchronous* XHR is *required* for tests or web
scraping. I have done testing with headless browsers myself a lot and
never needed *synchronous* XHR ever.

Also "web scraping" means first of all just to send requests and wait
for the result. There is no issue at all if this is done with
asynchronous XHR.

And why does the XHR to be synchronous?
