Automatic update from web-platform-tests Workers: improve exceptions in workers coverage This also aligns abrupt-completion.html with the specification as shared worker runtime exceptions do not propagate to the SharedWorker instances. Only an initial parse error will propagate to the creating SharedWorker instance. -- wpt-commits: daf5e97bc3132e6ea5beaa0105c878314bec8239 wpt-pr: 59652
