 {{{
 #!CommitTicketReference repository="" revision="51232"
 Widgets: Fix an “Invalid value” warning when adding a new widget in the
 Customizer.

 This fixes a regression introduced in [50996] where sites that have been
 opted-out of the block-based widget editor experienced an “Invalid value.”
 error when adding a new widget to a sidebar in the Customizer.

 This was caused by the early return value was changed to `null` from
 `$value` when set to an empty `array`, resulting in the widget being
 evaluated as invalid elsewhere.

 Fixes #53479.
