Comment:

 In [changeset:"46090" 46090]:
 {{{
 #!CommitTicketReference repository="" revision="46090"
 Accessibility: Comments: In `comment_form()`, remove `aria-describedby`
 attribute from the email field if there's no associated description in the
 `comment_notes_before` argument.

 The attribute is meant to communicate to user agents and assistive
 technologies that the element has a description. If the referenced
 description is missing, it will be flagged as failure by any automated
 accessibility checker tool and, most importantly, is potentially confusing
 for assistive technologies users.

 Props afercia, joedolson, dinhtungdu, donmhico, SergeyBiryukov.
 Fixes #47975.
