Since updating, switching to function keys per application stopped working

[arcadeperfect]

I have a rule to switch the media keys to function keys in specific apps. Since updating, it doesn't work.

Interestingly the event viewer indicates that the switch is working, but the software doesn't respond to the input, and the media key function happens anyway.

Meaning,
f12 returns this normally:
{"consumer_key_code":"volume_increment"},

With VSCode focussed, f12 returns:
{"name": {"key_code":"f12"},

However VSCode doesn't respond and the volume increases anyway.

If I set the media keys to function keys globally in system settings, they do behave as expected, always returning
{"name": {"key_code":"f12"},

Please try configuring it to send fn+f12.

I have the same problem and cannot fix it #4005

It appears to be working after implementing fn+f12

Thanks!
