Steps to reproduce

Not exactly clear on what’s causing this, but we’ve had to block Edge from Cyph since discovering about a month ago that basic XHR requests inside workers were throwing the error "Unexpected call to method or property access.". Specifically, requests made early on in our worker code work fine, but then at some point further down in the code they suddenly stop working for no apparent reason.

I’ve given up trying to reduce this down to an isolated test case, so for repro just open this page with a JS console open and wait for the breakpoint: https://msedge-test-dot-cyph-im-dot-cyphme.appspot.com
