I see:
assert_throws_dom: function "() => { history[method](new SharedArrayBuffer(), "dummy title"); }" did not throw

The subtests are failing for me but not due to lack of SharedArrayBuffer support.

>From Web Inspector, I can see that the test is serving the COOP+COEP headers:
Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Opener-Policy: same-origin

@Yusuke, I've enabled COOP + COEP by default only very recently. Maybe you tested on a build that didn't have them enabled yet?
