Highlight indicator as focused, not clicked.

Changes the highlight of the indicator when a promo is shown, to mimic
being focused/hovered rather than clicked.

This is done according to recommendation from UX to achieve a lighter shade
of the background color (promo is showing) in contrast to a darker shade
(when the bubble opens). This change provides the user with subtle visual
feedback.
