Using this Plasma component in an app causes the icons to disappear when using a dark
Plasma theme and a light color scheme, or vice versa. This patch fixes that by porting
away from the Plasma component and instead using a Kirigami icon to show the icons.
The patch also spruces up the visual presentation a bit.
