Dropdown item: support dialog and drawer props from buttons

[soerenengels]

Description

I want to extend an area with a dropdown and drawer definition. As I expected the following to work, I could not get the drawer to open from a PHP defined dropdown with drawer key as shown below. dialog is working for me. At Discord an alternative with a drawers/ prefixed link was proposed, that is working for me, but seems inconsistent.

[
  'pattern' => 'example/dropdown',
  'action'  => function () {
    return [
      [
        'text'   => 'Example link',
        'icon'   => 'link',
	'link' => 'https://getkirby.com/', // Works
      ],
      [
        'text'   => 'Example Dialog',
	'icon'   => 'chat',
	'dialog' => 'route/to/dialog', // Works
      ],
      [
        'text'   => 'Example Drawer (Expected behavior)',
	'icon'   => 'open',
	'drawer' => 'route/to/drawer', // Doesn't work
      ],
      [
        'text'   => 'Example Drawer (working)',
	'icon'   => 'open',
	'link' => 'drawers/route/to/drawer', // Works
      ],
    ];
  }
]

Expected behavior
Consistent keys in dropdown/button definition. Either prefixed link or additionally dialog AND drawer working.

Currently, I am less confused why drawer isn't working yet, but why dialog would be working already. Doubting my solution is right then, somewhere dialog needs to be supported already if it works.
