Display entire header in kmail 5.15.3

[Rainer Dorsch]

Hi, 

after upgrading from Debian buster to Debian bullseye and  kmail 5.15.3, it 
seems I cannot display the entire header of an email anymore.

Both the option in the View->Headers menu and the module in the settings seem 
to be gone.

Any hint or advice is welcome.

Thanks
Rainer
