Re: [csswg-drafts] [css-animations] Serialize all keyframe names as strings (#2435)

I am confused. :worried:

Quoting the new text:

  > The `<string>` should be treated as `<custom-ident>`, hence parsed as invalid if is one of the CSS-wide keywords or "default"

This is not what I understand from the above resolution, tests on WPT, and output in Firefox.

`"<css-wide-keyword>"`, `"default"`, `"none"`, `"1"`, `"not a custom ident"`, etc... are all valid on WPT and in Firefox, which serializes them as an identifier when possible. `normal` and `auto` are valid. `none` is invalid.
