Frequent "results not found" for Edge

[gsnedders]

e.g., see https://wpt.fyi/css/css-flexbox-1 with Edge@6048c3b213. Majority of tests are "(results not found)". I've seen this elsewhere, and it seems relatively common?

I ran in to this today with https://wpt.fyi/workers/interfaces/WorkerGlobalScope/onerror/propagate-to-window-onerror.html, which meant I had to manually test Edge for whatwg/html#1607
