The property config.xpack.infra.sources.default.fields.tiebreaker only appears to support a single field, and Kibana will show "There are no log messages to display." if it's missing.
Instead it should support multiple, the same as context:tieBreakerFields. Especially as there's no built-in solution to generate sequence numbers in logstash if they're missing.
A comma-separated list of fields to use for tiebreaking between documents that have the same timestamp value. From this list the first field that is present and sortable in the current index pattern is used.
Specifically I want to be able to set it to seq,_doc.
