Steps to reproduce: 1. Open kcm_mouse module 2. Under "General" tab, set "Button Order" to "Left Handed" via radio button (which works) 3. Reboot/restart session, mouse is right handed again, but, 4. Opening kcm_mouse still shows that the radio button is set to "Left Handed" 5. Reset to "Left Handed" works until session restart or reboot. NOTE: this bug seems similar to #87226
