Yes. document.execCommand("Stop")

I have no evidence to say anything sure here, but I doubt Web compat
requires transitions from "loading" to "complete". What actually
happens varies a lot.

Gecko and WebKit disagree.

Looks like Opera is alone with the non-aborting behavior. The spec is wrong.

Not in WebKit.

Probably.
