 #!CommitTicketReference repository="" revision="42024"
 Customize: Link `elements` prior to embedding to prevent possible errors
 when a control is associated with a non-existent section.

 Fixes issue specifically with attempting to access an orphaned control's
 `elements` immediately after it has been added. Normally this would not
 happen because a control would not be registered without a section, and
 also a control should only be interacted with once its `embedded` deferred
 has been resolved.

 Also harden logic for gathering list of deferred setting IDs.

 See #37964.
 Fixes #42330.
