Comment (by adpawl):

 I can confirm.

 '''Test settings:'''
 page_on_front: 1
 show_on_front: page
 page_for_posts: 9

 '''posts page (normal)'''
 page_id: 9
 is_home(): bool(true)
 is_page(): bool(false)
 is_preview(): bool(false)
 is_front_page(): bool(false)

 '''posts page (preview)'''
 page_id: 1
 is_home(): bool(false)
 is_page(): bool(true)
 is_preview(): bool(true)
 is_front_page(): bool(false)

 '''Cause''':
 '''class-wp-query.php'''
 {{{#!php
 <?php
 if ( $this->is_home && (empty($this->query) || $q['preview'] == 'true') &&
 ( 'page' == get_option('show_on_front') ) && get_option('page_on_front') )
 {
  $this->is_page = true;
  $this->is_home = false;
  $q['page_id'] = get_option('page_on_front');
 }
 }}}
