Description of the bug

When I set the icon theme with nwg-look, the systray icons still use default/hicolor icons, instead of using the ones from the icon theme.

Reproducing the issue

1. Open systray
2. use nwg-look to set icon theme
3. eww reload

Icon theme does not change

Expected behaviour

Systray icons should follow the new icon theme
