public function ViewEditForm::submitDelayDestination in Drupal 8

2. 10 core/modules/views_ui/src/ViewEditForm.php \Drupal\views_ui\ViewEditForm::submitDelayDestination()

Submit handler for form buttons that do not complete a form workflow.

The Edit View form is a multistep form workflow, but with state managed by the SharedTempStore rather than $form_state->setRebuild(). Without this submit handler, buttons that add or remove displays would redirect to the destination parameter (e.g., when the Edit View form is linked to from a contextual link). This handler can be added to buttons whose form submission should not yet redirect to the destination.

  // If there is a destination, and redirects are not explicitly disabled, add
  // the destination as a query string to the redirect and suppress it for the
  // current request.

    // Create a valid redirect if one does not exist already.
