Comment:

 In [changeset:"52015" 52015]:
 {{{
 #!CommitTicketReference repository="" revision="52015"
 Comments: Avoid reparenting during post deletion.

 Delete comments in a descending order by comment ID when deleting a post.

 This avoids the expense of additional database queries required to re-
 parent threaded comments that are themselves about to be deleted.

 Props Mte90, andraganescu, johnbillion, hellofromTonya, peterwilsoncc.
 Fixes #37703.
