How can I fix the iTunes 11 mini player that won't show the track name?

When I start the mini player in iTunes 11 on Mountain Lion, I do not see the expected track information which, when moused over, is supposed to change to playback controls:

Instead, the playback controls are permanently displayed and I can't find a way to show track info (aside from album artwork). Also, as shown in the screenshot below, whenever the mini player is the active window, the rewind button has a blue highlight.

The reviews that have appeared on the web, and Apple's keynote, suggest that this is not normal behaviour. Is it a bug that others are experiencing and is there a way of fixing it, apart from waiting for an update?

The answer is in the comments on this TUAW post. The keyboard focus on the mini player (indicated by the blue focus ring) is on one of the playback controls, which prevents them from hiding. Click the mini player background to bring it to the foreground, then press tab until the focus ring moves to the Up Next or Search icons, and track information will appear whenever the mouse is not over it.

Tabbing to the search or "up next" solves the track name visibility problem, but then it stops pressing space bar to play-pause.
