Commerce assumes filtered_html exists, but it may not.

In commerce_checkout_completion_message_pane_settings_form, there is a default to use the filtered_html type: $text_format = 'filtered_html';

If Drupal is installed using the minimal profile this format is not installed, and the user is shown a blank page on checkout. The full_html type is always available, perhaps that should be used by default? Alternatively, force this type to exist on install.

The filtered_html is hardcoded here:

modules/checkout/includes/commerce_checkout.checkout_pane.inc
67:    $text_format = 'filtered_html';
127:    $text_format = 'filtered_html';

modules/customer/includes/views/commerce_customer_ui.views_default.inc
96:  $handler->display->display_options['empty']['area']['format'] = 'filtered_html';

modules/line_item/includes/views/commerce_line_item.views_default.inc
93:  $handler->display->display_options['empty']['area']['format'] = 'filtered_html';

modules/order/includes/views/commerce_order_ui.views_default.inc
96:  $handler->display->display_options['empty']['text']['format'] = 'filtered_html';
376:  $handler->display->display_options['empty']['text']['format'] = 'filtered_html';

modules/product/includes/views/commerce_product_ui.views_default.inc
