Grok pattern for IPv6 not working with %{IPORHOST} - Azure Logs - Filebeat 7.14.1

Elasticsearch is failing to index events with a 400 error attempting to parse an IPv6 event in the Azure Platform Pipeline:

"status"=>400, "error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse field [source.ip] of type [ip] in document with id ''. Preview of field's value: '2405'", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"'2405' is not an IP string literal."}}}}}

This issue is similar to or also records at:
https://issueexplorer.com/issue/elastic/beats/28068

Testing an IPv6 Address against this pattern using https://grokdebug.herokuapp.com/ returns the same result, the first hex block of the IPv6 is returned as the hostname.

To workaround the issue specifically with the Azure ingest pipeline %{IPV6} was added as a first check sequence but the Grok pattern IPORHOST will need attention.
