Why is a DHCP suffix enforced from v5.2 on?

I have always and still are using Pi-Hole as my DHCP server, but since upgrading to this version (5.3), the client names in the dashboards (web), Top Clients (total) and Top Clients (blocked) are now being tagged/displayed, with the Pi-Hole domain name at the end, how to turn this off and display names as per the local DNS record for each client, without the pihole domain name?

Even in the Query log, client names are now also being tagged/displayed, with the Pi-Hole domain name.

I cant find an option to disable this type of display/function. Can someone please direct me and or advise, how to disable/turn this off?

Is this really required with a single Domain name in the Pi-Hole settings for DHCP? Not for me.

If people want to tag clients with a domain name, then do that through the local DNS setup for a client. Don't assume everyone wants to see client names tagged that way for display. For me at least (maybe not all),, its just an eye sore and waste of space.
