> WHATWG always just standardizes "whatever Chrome does".
It really ... doesn't. When the situation has arisen that Chrome has implemented an API for long enough for it to become entrenched in the web, it then discusses standardizing it (see also: https://compat.spec.whatwg.org/). But it's not blindly following Chrome, it's only in these special cases.
I've recently been involved in a couple of issues where browsers disagree with each other and/or the spec. Each time there's a discussion, and the best version of the behavior is chosen and worked into the spec. This best version is not always the Chrome version.
