Backend component property type of Set does not work

Description:

I develop my own plugin with custom Component. This component has property type of Set. This property has defined some options and default value too.

Default value is visible in backend are correctly, see first screenshot. (In CMS editor)

When I want to select another (non-default) options, none is actually selected. See second screenshot.

Steps To Reproduce:

<?php

use Cms\Classes\ComponentBase;

class ProductsList extends ComponentBase {

  public function defineProperties(): array
  {
    return [
      'productTypeExternalIds' ⇒ [
        'title' => 'Product types,
        'type' => 'set', # problem with set, e.g. dropdown works file, but I need multiple items selected
        'default' => [123],
        'required' => true
      ]
    ];
  }

  public function getProductTypeExternalIdsOptions(): array
  {
    return [
      123 => 'Some product',
      200 => 'Another product',
    ];
  }
}

Hmm ... It looks like it works when keys of options array are strings. E.g. option-123, option-200, ... It is necessary to parse the integer from key later.

Confirmed the same thing, the key values must be strings and then you can cast them to integers later, if necessary. Made a note to get this fixed in a later release. Thanks @maraerben !
