Re: [whatwg/dom] Do not dispatch a trusted event when target and reletedTarget are identical (#336)

> IMO if there is no normative behavior change being discussed then the exact spec mechanisms being used should be up to the discretions of the editors.

There is a behavior implication here that all events with related targets identical to target won't be fired. Given the UI events spec doesn't precisely specify whether related target is different from target(e.g. [mouseout](https://w3c.github.io/uievents/#mouseout)), it's permissible to have UA that fires `mouseout` with related target and target being identical today although it doesn't seem to happen in practice in common cases in major browsers.
