Describe the sample
Change placement to Right:

It's a bit weird that the content isn't stretched to put the panel on the right-side next to the options.

It get's odder when you change the display mode to CompactInline or CompactOverlay as the icons don't show up:

(Also changing the DisplayMode to CompactInline doesn't appear to work the first time, as IsPaneOpen is still on, looks like changing to the overlay modes turns it off as well at the same time, so it's inconsistent here.)
