Icons in Plasma Styles

In Plasma 5, the icons shown in various parts of Plasma widgets (but not apps) can come from one of two places: the active icon theme, or the active Plasma style.

For Plasma 6, we’re removing this questionable feature, and icons in Plasma widgets will always come from the systemwide icon theme. Much simpler, much more user-comprehensible, much better visual results 99% of the time.

I've tried to give Plasma a fair shot a few times, but, among other issues, I'm not a fan of Breeze and I found the theming functionality overwhelming and difficult to navigate. Mainly I could never figure out which themes certain elements were attached to. This is a big example and I'm glad to see them changing it.
