Automatic update from web-platform-tests Fix remaining preload tests flaking on wpt.fyi This is a follow-up to https://github.com/web-platform-tests/wpt/pull/15075. https://crrev.com/c/1436777 successfully fixed the wpt.fyi flakiness for link-header-preload-srcset.tentative.html and link-header-preload-nonce.html. This patch fixes that for the remaining preload tests. - Use step_timeout instead of dummy.js?pipe=trickle, because dummy.js?pipe=trickle may be loaded from cache with no delay. - Replace verifyNumberOfDownloads() with - verifyNumberOfResourceTimingEntries() if possible - A new helper function verifyLoadedAndNoDoubleDownload() that doesn't fail if the resource was already cached before running the test.
