Auto merge of #16087 - jdm:testimprovement, r=metajack

Browse source 
Don't create a new XHR until the previous one is complete.

This test often times out when run under rr, because the event loop gets flooded with timer events that initiate XHRs before the previous XHR has completed. Additionally, we're running the event handler up to three times per XHR, which is just silly.
