Description Tim Nguyen (:ntim) 2022-11-28 00:43:24 PST 
Currently, we support `none`/`auto`/`ink` for the `text-decoration-skip` shorthand. Currently, `ink` is an alias for `auto`.

However, the spec only defines 2 values: https://w3c.github.io/csswg-drafts/css-text-decor-4/#text-decoration-skipping

We should remove `ink`.

I expect web compat fallout to be close to none, given:
- `ink` has the same behavior as `auto` (which is the default value), so the only scenario this would cause a behavior change is if one ancestor style has `text-decoration-skip: none`
- Chrome has unshipped the entire `text-decoration-skip` property, Firefox does not support it.

For books, it would be trivial to patch this from a content script if really needed, although I suspect fallout is extremely small.

Ah, it seems like the whole point of the `ink` value was for `-webkit-text-decoration-skip: ink`.
