Comment:

 In [changeset:"38166"]:
 {{{
 #!CommitTicketReference repository="" revision="38166"
 Customize: Prevent customize-preview-widgets JS errors in preview if a
 sidebar is registered with empty before_widget/after_widget params.

 Selective refresh will not be available for widgets when they lack these
 params, so previewing will fallback to full page refreshes. Sidebars
 registered as such should be rare so this accounts for an edge case.

 Fixes #37478.
