The preprocess_comment filter is never run when an empty comment is submitted.

The empty check happens before wp_new_comment() is called and the preprocess_comment filter is applied in wp_new_comment()

This page in the documentation, Using custom attributes in menus and taxonomy archives indicates

Custom attribute slugs are prefixed with ‘pa_’, so an attribute called ‘size’ would be ‘pa_size’

However, the behavior I appear to be seeing is global (i.e. taxonomy) based attributes are prefixed with pa_ and custom (i.e. local) attributes are not, which I believe is the opposite of what the documentation says.

For clarification, I'm referring to a custom (i.e. local) attribute as one I add to a specific product using the Custom Product Attribute Add button.
