…function logic Before this commit the `flatten(..)` function failed to deliver what it promised. Namely, it entered into Mixed paths of objects. Update validator, on its side, did not pass the casted doc schema into `flatten(..)`. If the casted doc contained a large Mixed field, all its paths were added into the list of updated paths. They were lated ignored by now removed check for schemaPath type, but performance was already hurt. This commit makes sure that inner sub-paths of Mixed paths are not included into the array of paths at all, thus no further checks of that are necessary, and the performance is restored. Fixes Automattic#8093
