Herdr Windows key prefix config (ctrl+comma) not working

I’m using herdr on Windows and trying to set Ctrl + , as the prefix.
In ~/.config/herdr/config.toml I tried:

[keys] prefix = "ctrl+comma" and also "ctrl+,".

Other prefixes like ctrl+q and ctrl+g work correctly after restart. However, when using ctrl+comma, the key is not captured by herdr and instead triggers PowerShell’s completion menu (same as Ctrl + Space).
