KDE 6 icon troubles.

[AlekEagle]

KDE 6 released yesterday and introduced a new interesting behavior regarding icons. Specifically tray icons indicating the status of system attributes like volume and battery use static candy icons.

Also experiencing this, and it's making the theme unusable for me, because I am confused which icon is the media player and which is the volume control.

Here's a screenshot that showcases the problem

As you can see, some icons are pulled from Breeze, and some from Candy Icons

The issue is due to an annoying change to how icons on the panel are pulled: before, it used to pull them directly from the Plasma theme, NOT the icon theme.
However, this changed in KDE6, and it now pulls them all from the icon theme, causing issues with older themes as most of them use new names (either "[name]-tray" or using the symbolic version "[name]-symbolic]")

This would, no doubt, cause some head scratching as to how to design those new icons
Now, thankfully, the Sweet Plasma theme is also owned by EliverLara, so pulling the icons from there seems like the best solution
