Entity Autocomplete element expecting an array, but getting a scalar value for target_id instead

When using Layout Builder with a View block display (having configuration parameters added by a patch from #2657060: Add Configure Filter functionality to block views configuration. → ) containing a footer link to a Page display on the same view with matching exposed filters, the linked page expects each filter to be an array containing a target_id key with a numeric ID, but a scalar value is provided instead.

The following error is observed when saving the block configuration in Layout Builder:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /layout_builder/update/block/overrides/node.XXX/0/content/UUIDv4?destination=/node/XXX/layout&_wrapper_format=drupal_dialog.off_canvas&ajax_form=1
StatusText: parsererror
ResponseText: TypeError: Argument 1 passed to Drupal\Core\Entity\Element\EntityAutocomplete::Drupal\Core\Entity\Element\{closure}() must be of the type array, null given in Drupal\Core\Entity\Element\EntityAutocomplete::Drupal\Core\Entity\Element\{closure}() (line 80 of /app/web/core/lib/Drupal/Core/Entity/Element/EntityAutocomplete.php).

Once the layout is saved, the page becomes inaccessible due to the following error:
