Summary worker and other values are valid keyword for the 'as' property in link preload

When a document contains: <link rel="preload" href="main.js" as="worker" /> Safari reports: <link rel=preload> must have a valid `as` value Probably a couple of tests are missing from https://wpt.fyi/results/html/syntax/speculative-parsing/generated/page-load?label=master&label=experimental&aligned&view=subtest&q=preload or https://wpt.fyi/results/fetch/metadata/preload.https.sub.html?label=master&label=experimental&aligned&view=subtest&q=preload or in https://wpt.fyi/results/preload/reflected-as-value.html?label=master&label=experimental&aligned&view=subtest&q=preload The fetch spec definition: https://fetch.spec.whatwg.org/#concept-request-destination > A request has an associated destination, which is the empty string, "audio", "audioworklet", "document", "embed", "font", "frame", "iframe", "image", "manifest", "object", "paintworklet", "report", "script", "serviceworker", "sharedworker", "style", "track", "video", "worker", or "xslt". Unless stated otherwise it is the empty string. > > A request’s destination is script-like if it is "audioworklet", "paintworklet", "script", "serviceworker", "sharedworker", or "worker". It seems there are a couple of values which are not defined such as video for example.
