'#empty_value', '#empty_option' does not work properly

Unfortunately v1.9.0 did not fix issue 3123254 → properly.

Code example from previous issue is not rendered as should be:

$form['name'] = array(
  '#type' => 'select2',
  '#title' => 'Some title',
  '#options' => [1 => 'One', 2 => 'Two'],
  '#empty_option' => '[custom empty value]',
  '#empty_value' => -1,
  '#placeholder' => 'this property is ignored',
);

Result: http://prntscr.com/uizrxp
'#placeholder' property is working now, but there is an item with empty string added to dropdown (it should have '#empty_option' property value as a content).

Trying to remove '#placeholder' property:

$form['name'] = array(
  '#type' => 'select2',
  '#title' => 'Some title',
  '#options' => [1 => 'One', 2 => 'Two'],
  '#empty_option' => '[custom empty value]',
  '#empty_value' => -1,
);

Result: http://prntscr.com/uizuc7
'#empty_option' property is rendered as a placeholder now (what is fine), but there is still an item with empty string in dropdown (should have '#empty_option' property value as a content too).

Just a notice: my patch ( https://www.drupal.org/files/issues/2020-04-09/empty_option-3123254-9.patch → ) from issue 3123254 was working for 1.8.0. So may it should be merged with accepted patch (https://github.com/thunder/select2/pull/87/files) somehow.

Thank you!
