Description

When I set up the remapping for the first time, it worked flawlessly. After going to standby, it still worked but all the F keys were shown on the touchbar when the remapped FN key was pressed.

Edit: After restarting Karabiner, it works again. But breaks as soon as it goes to standy.

How to solve this?

Research direction
The issue occurs after system standby, suggesting a bug in how Karabiner re registers FN key remapping upon wake. Investigate power management notifications and the callback that reinstates keyboard event taps. Review comments for workarounds and examine code in 'KarabinerKit' or 'Karabiner VirtualHIDDevice' related to touch bar control.
