Comment:

 In `46124.2.patch`, a conditional statement searches for either of these
 two items:

 1. a customized header "alt_text" value (using a filter not yet available
 - see tickets #38942 and #46134)
 2. an uploaded image's "attachment_id" to take its alt text, if provided
 (it's possible but not easy to set this yet - see ticket:46127)

 Then if neither is found, the alt text is simply empty.
