The 'Details' bar when active doesn't use theme colours in configurable theme

[Kristina Hoeppner]

When you use the configurable theme, the 'Details' bar when clicked on a page uses green instead of a theme colour or a neutral colour (see attachment).

to test:

1. On a page, add a 'Text block'.
2. View the page and click the 'Details' icon (magnifying glass)
3. Click 'Quick edit' on the text block.
