A newtab test closes its about:newtab tab, tabbrowser immediately starts
loading a replacement preloaded about:newtab with docShellIsActive false, and
ComponentPerfTimer mounts in it and calls requestAnimationFrame. That keeps
nsRefreshDriver ticking at the full vsync rate without running the request, so
vsync stays enabled and browser-test.js's ensureVsyncDisabled can time out.
