Theming a view that's been rendered to a variable

Has anyone been able to do this? The more I play with it the more strange things I'm seeing like
's thrown in to keep the view a certain width, but only in certain fields. I've looked through the code, but I'm not seeing where the div tags are getting stripped out or where the line breaks are being added.

Replace the function option_definition() with the following in rules_views_executor_plugin_display_rules_executor.inc

  function option_definition() {
    $options = parent::option_definition();

    $options['displays'] = array('default' => array());

    // Overrides for standard stuff:
    $options['style_plugin']['default'] = 'rules_views_executor_style';
    $options['row_plugin']['default'] = 'rules_views_executor_row_ruleset';
    $options['defaults']['default']['style_plugin'] = TRUE;
    $options['defaults']['default']['style_options'] = TRUE;
    $options['defaults']['default']['row_plugin'] = TRUE;
    $options['defaults']['default']['row_options'] = TRUE;
    $options['username']['default'] = 'Rules executor';
    $options['permissions']['default'] = array(
      'access comments',
      'administer comments',
      'access content',
      'administer nodes',
      'administer users',
    );

    return $options;
  }
