Re: [whatwg/dom] Standardize certain Microsoft event extensions (#334)

> WebKit ToT matches the spec and Gecko in this regard.

Yeah, verified w/ https://miketaylr.com/bzla/beforeunload-3.html (where `e` isn't returned`). But it doesn't match in https://miketaylr.com/bzla/beforeunload-2.html (where `e` is returned).

@cdumez was there any motivation to move WebKit to this behavior (other than spec compliance)? If there are sites that depend on it, that would be useful information, especially given the split in behavior between Gecko/WebKit (Trunk)/Presto and Blink/Edge/IE.
