[Forminator] Add placeholder to the select field as a default value

I am trying to set up a simple form with forminator pro. But when I enter a placeholder into the placeholder field in a single select field, the placeholder doesn’t show and the first select option is showing up instead. It could be solved really easily by wpmudev developer team, by adding another disabled option to the select field with NO set value and label being the entered placeholder input.
I even wrote a fix. Would you like to pass it to the developer so he can implement it?

if ( ! empty( $placeholder) && 'enable' !== $search_status ) {
$options_markup .= '<option disabled value selected>' . $placeholder . '</option>';
}

Add this code after line 230 in following file: /wp-content/plugins/forminator/library/fields/select.php
