Hmm. Is this necessary?

My view is that this kind of test isn't very valuable in LayoutTests, but if any
other engine implemented these, then submitting it to web-platform-tests as a
historical.html test can provoke others to also remove. Filing bugs of course
also helps. Example:
https://github.com/w3c/web-platform-tests/blob/master/dom/historical.html

 
-shouldBe("listener.speedOfSound", "343.3");
-evalAndLog("listener.speedOfSound = 400");
-shouldBe("listener.speedOfSound", "400");
-
-evalAndLog("listener.setVelocity(0, 0, 0)");
-
-evalAndLog("panner.setVelocity(0, 0, 0)");
+shouldThrow("listener.setVelocity(0, 0, 0)");

Checking that the method doesn't exist would be more clear.

+shouldThrow("panner.setVelocity(0, 0, 0)");
