1. 10.3.x modules/social_features/social_landing_page/social_landing_page.module \social_landing_page_field_widget_block_field_default_form_alter()

Implements hook_field_widget_WIDGET_TYPE_form_alter().

When rendering the block form inside paragraphs, the #states will not work due to different name parameter, since it's nested inside the paragraph field. We need to alter the form, so that the #states will match the new html markup provided by paragraph. We only do this for 'Override title' field.
