External DNS, Azure Private-DNS, combine-fqdn-annotation produce douplicate IP

[chris8205]

What happened:
If fqdn-template is used, and combine-fqdn-annotation is set,
external dns would like to update the A record to the same ip ex: A ---> IPv4 --> 100.50.0.48;100.50.0.48
but a record can't get multiple time the same ip

seems, that there is a "filter" missing to prevent if the template match the service annotation:
external-dns.alpha.kubernetes.io/hostname: mytestworkload.mytestnamespace.myzone

external-dns-privatezone-xxxxxxxxxxxxxx {"level":"error","msg":"Failed to update A record named 'mytestworkload.mytestnamespace' to '100.50.0.48;100.50.0.48' for Azure Private DNS zone 'myzone': PUT https://management.azure.com/subscriptions/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/resourceGroups/xxxxxxxxxxxxxxxxxxxxx/providers/Microsoft.Network/privateDnsZones/myzone/A/mytestworkload.mytestnamespace\n--------------------------------------------------------------------------------\nRESPONSE 400: 400 Bad Request\nERROR CODE: BadRequest\n--------------------------------------------------------------------------------\n{\n "code": "BadRequest",\n "message": "The list of record sets of type 'A' may not contain multiple entries with the same 'ipv4Address'."\n}\n--------------------------------------------------------------------------------\n","time":"2024-06-17T07:40:20Z"}
