+++ This bug was initially created as a clone of Bug #1213932 +++ This is a follow up Bug 1213932. See: https://bugzilla.mozilla.org/show_bug.cgi?id=1213932#c15. The situation is that a page at https://foo.com/index.html loads a Worker at https://foo.com/lib/background.js, and then does `.register('sw.js', { scope: './lib' })`. In this case the log won't show up after Bug 1213932, since the scope won't match https://foo.com/index.html. We would need to iterate all workers and match a SW message on their scriptURLs also.

As per https://bugzilla.mozilla.org/show_bug.cgi?id=1223116#c7, Bug 1223116 took a step towards fixing this but we also need to extend the shouldReportToWindow logic to include the Worker's parent document in the list of registering documents. And this should be somehow part of fixing Bug 1032521.
