[editing] The web doesn't need another badly implemented API (#88)

Excuse me for raising a voice that goes against the entirety of what you're gathering here to do, but I must say what I feel is the truth.

There is no need for such an API. I feel that the `contentEditable` stuff should just be deprecated.

For two reasons:

1. There is no way that browsers will implement such a complex API in a reasonably consistent manner.
1. It is possible to write client code that implements all of this, without using any `contentEditable` at all.
