When a drupal form is opened in a dialog, the submit buttons are automatically turned into jquery ui dialog buttons.
Sometimes this is not wanted and the drupalAutoButtons options is supposed to control if this is needed or not. Setting this at FALSE from the PHP doesn't do anything, buttons are still created.
Patch fixes the missing js that makes this option work as expected. This can be tested with the outside-in module. Before patch submit buttons are at the bottom of the dialog styled like jQuery dialog buttons, after the patch they're regular form submit buttons.
