It does not work on Firefox 45.0.2, Nightly48.0a1 and Chrome 51.0.2704.7 dev-m.

It works on Chrome 49.0.2623.112 m and 50.0.2661.75 m.

Chrome closed as by design because it's apparently not a trusted event: https://bugs.chromium.org/p/chromium/issues/detail?id=604182

Guess this may be spec-compliant after all?

It is definitely spec compliant. 'click' event is the only special case where untrusted events are supposed to trigger default handling (I can't recall if that is spec'ed properly atm, but it is sort of a side effect of using click() method on elements.)
