public ViewEditForm::submitDelayDestination($form, FormStateInterface $form_state)
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.
