Weston Ruter 610b1f05de 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.
