Hello Stefan,

Sincerely, I thought this bug was closed a long time ago.

The rationale of this proposal was to handle any possible face spec returned by (get-char-property (point) 'face) in `faces--attribute-at-point' (by using `face-attributes-as-vector'), because in some corner cases the current implementation can return a wrong attribute value, as illustrated by the simple recipe in my initial post.

However, if I correctly understand Eli's objection, I agree that the face spec in my recipe can be considered as invalid, and not supported by `faces--attribute-at-point', even if a such face spec is an accepted text property, probably for backward compatibility.

Thanks
