16683	Balloonpanel should handle non-existent styles.	kkrzton		"== Steps to reproduce ==

1. Go to https://www.webtrix.be/moonocolor/ (you can also use build with this or different skin downloaded from http://ckeditor.com/builder).
2. Switch to source mode and paste html:

{{{
<h1>Content Accessibility Matters</h1><p><img src=""https://c.cksource.com/ac/2/images/accessibility-matters-01.png"" style=""float:right"" /></p>
}}}

3. Switch back to WYSIWYG mode.
4. Click `a11ychecker` button to run Accessibility Checker.

== Expected result ==
The Accessibility Checker dialog opens. It is styled and positioned properly.

== Actual result ==
The Accessibility Checker dialog opens. It is not styled and positioned properly.

== Other details (browser, OS, CKEditor version, installed plugins) ==
The cause of this issue is the fact that `balloonpanel` has only 3 supported skins (https://github.com/ckeditor/ckeditor-dev/tree/master/plugins/balloonpanel/skins) and for any other skin, invalid CSS is loading (see attached screenshot) so there is no styling applied to `ballonpanel` (for its insides, which are handled by `a11ychecker` plugin, the default skin is loaded, which is `moono-lisa` since 4.6.0).

I think `balloonpanel` should use default styles if stylesheet for specific skin is not present."	New Feature	confirmed	Normal		General
