<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>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.
