Example:

• Open demo project HOME in page editor.
• Scroll down to the teasers under the stage.
• Select the LINK LIST area under the Standard Article.
  > The "INTERNAL PAGE TEASER" editbar remains grey.

See linked ticket 205 for description of how the parent of the selected element should be displayed.

When the selected element is a component, and the parent is an area, then the css class "childFocus" is applied to the parent.
A css class such as "childFocus" should be applied to the parent also in the case that the selected item is an area, and the parent is a component.

In CSS there is no way to select the parent of an element, therefore in code a css element must be applied.

Probably the solution will be to make FocusModelImpl.setComponentSelection() more like FocusModelImpl.setAreaSelection()
