If [propertyTabPage:indicator-activatable] is set to TRUE, the indicator
icon can act as a button.

If set to TRUE, [classTabBar] will display a spinner in place of icon.
If the page is pinned and [propertyTabPage:indicator-icon] is set, the

[classTabBar] will display a glow under the tab representing the page if
set to TRUE. If the tab is not visible, the corresponding edge of the tab
bar will be highlighted.
