There was a problem hiding this comment.
Instead of adding subfeatures, we should be able to unmark the implementations as partial.
The partial implementation guidelines require inconsistent support between browsers, which does not seem to be the case here.

This is a bit of a weird one. These are currently marked 'partial' in Chrome & Firefox because they don't support the
onfocusoutevent handler property. However, those properties are nonstandard - they're not defined in the HTML spec.These events are somewhat spec'd in UI Events, but the handler properties are not.
Although the data guidelines explicitly recommend using partial in these cases, it seems incorrect to apply this rule in cases where the handler property is nonstandard.
Marking other browsers as 'partial' because one browser implements a nonstandard extension to the feature seems… bad.
There was an attempt to add these to the spec, but it stalled in 2024 whatwg/html#10235.
