I think DOM:Worker might be the proper component for this bug.


Component: Networking → DOM: Workers

https://searchfox.org/mozilla-central/rev/94d7c959115c03ea1e9406d6105b36cabe63775d/dom/xhr/XMLHttpRequestWorker.cpp#2174 looks bogus.

Blob::Create may return null, so mResponseBlob can be null and GetOrCreateDOMReflector isn't null-safe
