When posts/ and threads/ do, editor/dialog doesn't get its style overridden if the parent node has the "Override user style choice" option set to a different than the default style.
- Edit a Node and set the "Override user style choice" to a random style. Make sure it has different color variations from the default one.
- Start editing a post in any of its threads. Style inheritance has worked well till now.
- Click on any Dialog triggering button in your WYSIWYG. Dialog opens with the default style, without respecting the parent one.
