Re: [whatwg/dom] classes are compared without Unicode normalization (#793)

Sorry for the sloppy formulation of the issue.

The issue is not that the DOM spec compares identifiers code point by code point. Indeed, that method of comparison is recommended by [CHARMOD](https://www.w3.org/TR/charmod-norm). The issue is that the spec says it does a ‘case-sensitive’ comparison, which usually means something else. CHARMOD calls the comparison that the DOM does ‘case-sensitive matching without Unicode normalization’. With the name ‘case-sensitive’, people will expect it to do more than it does.

The I18N WG is considering raising an issue about the name on the Infra spec or on the HTML spec.

In the mean time, maybe the DOM spec can add a warning that this case-sensitive comparison does not include Unicode normalization?
