Last notification area icon not repaint when switching from big to small icons

reactos-bootcd-0.4.15-dev-7322-g3558b7b-x86-gcc-lin-dbg following fix of CORE-19380 by anonanon using https://github.com/reactos/reactos/commit/77653462a9503f126c4fdd839cb791aeb03daded

• Use big icons

• Revert to small icons : Keyboard system tray notification area icon not repaint and looks like a "half" network icon

• This is not specific to kbswitch : if "sound" icon is disabled and re-enabled, it's then the right most and gets affected while kbswitch is then no longer affected :

• Mouse over forces correct repaint

Nothing in log.
