Incident assignees are managed as follows:
If both incidents have been assigned, the merged incident takes the target incident assignee.
If both incidents are unassigned, the merged incident remains unassigned.
If the target incident is assigned and the source incident is unassigned, the merged incident takes the target assignee.
If the target incident is unassigned and the source incident is assigned, the merged incident takes the existing assignee.
In the merged incident, all source context data is lost even if the target incident does or doesn't contain context data. If the target incident contains context data, that context data is preserved in the merged incident.
